Question

in an experiment the probablility that event A occurs is 3/7 the probability that event B occurs is 1/5 and the probabliity that events A and B both occur is 1/8

Answer 1

In order to calculate the probability of A given B, we can use the formula:

`P(A|B)=(P(A\cap B))/(P(B))`

So we have that:

`P(A|B)=((1)/(8))/((1)/(5))=(1)/(8)\cdot5=(5)/(8)`
