The probability that Elise studies for a science test and passes it is 0.8. The probability that she studies

is 0.9. If Elise studies, what is the probability that she will pass the science test?

Solution

Here,

P(pass and studies) = 0.8
P(studies) = 0.9

Thus,

P(pass|study) = P(pass and studies) / P(studies)

= 0.8/0.9

= 0.888888889 [answer]
