struggling with this could use some help + work explination, i havent been to class in weeks!

Answer 1

The value of P(B)=17 for the given value P(A or B) = 13, P(A)= 14, and P(A and B) = 18.

What is probability?

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Here is the formula for the probability of an exclusive event:-

$P(AUB)=P(A)+P(B)-P(A\cap B)$

$13=14+P(B)-18$

$P(B)=17$

hence the value of P(B)=17 for the given value P(A or B) = 13, P(A)= 14, and P(A and B) = 18.
