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

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
Answer:
The answer is 0.65
