A magician showed a magic trick where he picked one card from a standard deck. Determined what the probability is that the card will be a red color or a queen card?

Answers

Answer:

7 / 13

Step-by-step explanation:

The number of cards in a standard deck = 52

Number of red cards in a deck = 26

Number of queens in a deck = 4

Selecting a card at random ;

Probability of picking a red card ;

P(red card) = number of red cards / number of cards in deck

P(red card) = 26 / 52

P(queens card) = number of queens / number of cards in deck

P(queens card) = 4 / 52

Number of red queen cards = (red n queen) = 2

P(red or queens card) = P(red) + P(queens) - P(red n queen)

P(red or queens card) = 26/52 + 4/52 - 2/52

= (26 + 4 - 2) / 52

= 28 /52

= 7 / 13

Nate downloaded a free virus detection program, which reported that his computer is infected with a virus. The editors of a tech magazine reviewed the effectiveness of the free program by running it on 500 computers, with 8% of those computers known to be virus-infected. Their findings are summarized in the two-way table. Virus Reported Virus not Reported Infected 28 12 Not Infected 94 366 Which statement is supported by the data? A. The magazine's review suggests Nate should trust the program's report because the probability that the scan result is a false positive is only 7.11%. B. The magazine's review suggests Nate should use a different detection program because the probability that the scan result is a false positive is 77.05%. C. The magazine's review suggests Nate should use a different detection program because the probability that the scan result is a false positive is 22.95%. D. The magazine's review suggests Nate should use a different detection program because the probability that the scan result is a false positive is 92.89%.

Answers

Answer: 77.05%

Step-by-step explanation:

.

The magazine's review suggests Nate should use a different detection program because the probability that the scan result is a false positive is 77.05%.

From the question we are told that:

Sample size n=500

Know Virus infection r=8\%

The data can be represented in the Table below a

[tex]\begin{tabular}{lllll}S/N & Reported & Not reported & Total \\Infected & 28 & 12 & 40 \\Not Infected & 28 & 36&460\\Total &122&378&500\\\end{table}[/tex]

Therefore the False Positive can be Mathematically represented as

[tex]FP=\frac{94}{122}[/tex]

[tex]FP=0.7705[/tex]

[tex]FP=77.05\%[/tex]

In conclusion we can say that  The magazine's review suggests Nate should use a different detection program because the probability that the scan result is a false positive is 77.05%

Therefore

Step-by-step explanation:

A researcher wished to compare the average amount of time spent in extracurricular activities by high school students in a suburban school district with that of high schoolers in a school district of a large city. The researcher obtained an SRS of 60 high school students in a large suburban school district and found the mean time spent in extracurricular activities per week to be x1 = 6 hours, with a standard deviation s1 = 3 hours. The researcher also obtained an independent SRS of 40 high school students in a large city school district and found the mean time spent in extracurricular activities per week to be x2 = 4 hours, with a standard deviation s2 = 2 hours. Let u1 and u2 represent the mean amount of time spent in extracurricular activities per week by the populations of all high school students in the suburban and city school districts, respectively. Assume the two-sample t-procedures are safe to use.
With a level of 5%, test the hypothesis that the amount of time spent on extracurricular activities is no different in the two groups.
For the problem above, a 95% confidence interval for u1-u2 is (use the conservative value for the degrees of freedom)

By transcribing and translating cach gene sequence, you will determine both where the mutation is located and what type of mutation has occurred. Finally, you will determine how the gene was changed and how it affected the person's phenotype. Procedure: 1) Each student will analyse one of four genes on the back of this sheet: TYR, OCA2, TYRP-1, or SLCASA2 Each student will have a different gene and be responsible for reporting their findings to the other group members 2) Fach form has an original DNA strand and 3 different mutated strandt. For cach, you will transcribe the mRNA sequence and then translate the mRNA into the amino acid sequence (AA). 3) With a colored pencil, you will then do the following . First, circle the mutation() on cach of the three mutared strands that differ from the original DNA strand at the top of your form. (Note: not all sequences start at beginning of gene.) . Second, lightly shade over cach codon that differs in the mRNA strand from the original mRNA strand at the top of your form Lastly, lightly shade over each amino acid that differs in the amino acid sequence from the original amino acid sequence at the top of your form .
