If A and B are independent events with P(A) = 0.5 and P(B) = 0.5, then P(A ∩ B) a. is 1.00. b. is 0.5. c. is 0.00. d. None of th

erastova [34]

Answer:

The answer is (d) "None of the these alternatives are correct"

Step-by-step explanation:

If two events A and B are independent, the probability of the intersection $P(A\cap B)$ is defined as:

$P(A\cap B)=P(A)\cdot P(B)$

Therefore, in the exercise:

$P(A\cap B)=P(A)\cdot P(B)=0.5\cdot 0.5\\P(A\cap B)=0.25$

which give (d) "None of the these alternatives are correct"
