Question

P(a)=0.50 p(b)=0.30 and p(a and b)=0.15 what is p(a or b)

Answer 1

Answer:

Option C is correct

P(A or B) = 0.65

Step-by-step explanation:

Given:

P(A) =0.5

P(B)=0.30

P(A and B) =0.15

( The probability of the happening of both independent events will be there product) P( A and B ) =P(A).P(B)

Solution:

To find the probability  of the Happening of event A either event B  we will use the following formula

P(A or B) = P(A) + P(B)-P(A and B)

                  = 0.5 + 0.3 - 0.15

                  =0.65
