Question

Find the value of COS
If P(A) =7/13 ,P(B) = 9/13 and P(A U B) =12/13, then P(AIB).
​

Answer 1

to the gym today and it is a great day and night with my family is going to write a letter to the gym

Answer 2

P(AUB)=P(A)+P(B)-P(AintersectionB)

12/13=7/13+9/13-P(A int B)

find

P(A int B)

P(A/B)=P(A int B)/P(B)
