If a fair coin is tossed, the probability that it will land heads up is ½. Olivia tosses a coin 4 times, and it lands on heads 4

consecutive times. Which statement below is true?
A. If Olivia tosses the coin a fifth time, it will land on heads, because the experimental probability of landing on heads is 100%.
B. If Olivia tosses the coin a fifth time, it will most likely land on heads because the fifth toss is dependent on what happened during the first 4 tosses.
C. If Olivia tosses the coin a fifth time, there is a ½ probability that it will land on heads, because it is an independent event, and it does not matter what happened during the first four tosses.
D. If Olivia tosses the coin a fifth time, there is a 0% chance that the coin will land on heads.

Consider two medical tests, A and B for a virus. Test A is 90% effective at recognizing the virus when it is present, but has a

P(V|A) is not 0.95. It is opposite:

P(A|V)=0.95

From the text we can also conclude, that

P(A|∼V)=0.1

P(B|V)=0.9

P(B|∼V)=0.05

P(V)=0.01

P(∼V)=0.99

What you need to calculate and compare is P(V|A) and P(V|B)

P(V∩A)=P(A)⋅P(V|A)⇒P(V|A)=P(V∩A)P(A)

P(V∩A) means, that Joe has a virus and it is detected, so

P(V∩A)=P(V)⋅P(A|V)=0.01⋅0.95=0.0095

P(A) is sum of two options: "Joe has virus and it is detected" and "Joe has no virus, but it was mistakenly detected", therefore:

P(A)=P(V)⋅P(A|V)+P(∼V)⋅P(A|∼V)=0.01⋅0.95+0.99⋅0.1=0.1085
