Question

If P (A)=0.57, P (B) =0.7, And P (A And B) =0.52, Find P (Aor B).

Answer 1

To find P(Aor B), substitute P(A), P(B), and P(A AND B) into the formula P(Aor B) = P(A) + P(B) - P(A AND B). The probability of event A or event B occurring is 0.75.

Step-by-step explanation:

To find P(Aor B), we can use the formula P(Aor B) = P(A) + P(B) - P(A AND B).

Given that P(A) = 0.57, P(B) = 0.7, and P(A AND B) = 0.52, we can substitute these values into the formula:

P(Aor B) = 0.57 + 0.7 - 0.52 = 0.75.

Therefore, the probability of event A or event B occurring is 0.75.
