Question

The probability of event A occurring is 50%, and the probability of event B occurring is 25%. Events A and B are nonsimultaneous events. What is the probability that event A occurs but event B does not occur?

Answer 1

p(a) = 0.5
p(b) = 0.25

p(not a) = 1-0.5 = 0.5
p(not b) = 1 - 0.25 = 0.75

Now p(a and not b) = p(a) * p(not b)
You can get the answer now!

Answer 2

so the answer is 0.375?

Answer 3

Thank YOU!!!!!

Answer 4

0.5 *0.75 = 0.375
