Question

If P(A)=1/3 and P(B)=1/4,what is P(A or B)?

A) 1/12

B) 5/12​

C) 7/12

D)1/2

Answer 1

The probability of A or B occurring is 7/12 (C).

Step-by-step explanation:

To find the probability of A or B occurring, we can use the formula:

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

Plugging in the given values:

P(A or B) = (1/3) + (1/4) - (1/3)(1/4) = 4/12 + 3/12 - 1/12 = 7/12

Therefore, the probability of A or B occurring is 7/12 (C).
