If A and B are two mutually exelusive events of a random experiment and P (not A)=0.45, `P(A cup B)= 0.65`, then find P(B).

If A and B are mutually exclusive events then P(AcapB)= ___.

If A is an event of a random experiment such that P(A) : P(barA) = 7:12 then find P(A).

If A and B are two events associated with a random experiment for which P(A) = 0.35, P(A or B) = 0.85, and P(A and B) = 0.15. Find (i) P(only B) " " (ii) P(barB)" " (iii) P(only A)

If P(A)=0.45,P(AcupB)=0.75 and P(B//A)=0.5 , findP(B):

The probability of an event A occurring is 0.5 and B occurring is 0.3 . If A and B are mutually exculusive events , then find the probability of (i) P (A cup B) , (ii) P ( A cap bar(B))

Given A and B are mutually exclusine events P(not A)= 0.35 P(AcupB)=0.85 . Find P(not B).
