Answer:

P(A and B) = 0.21

Step-by-step explanation:

Two events are said to be independent when the occurrence of event 1 does not affect the occurrence of event 2

Given two probabilities A and B whose probabilities are given as follows

P(A) = 0.3, P(B)  = 0.7

P(A and B) is calculated as follows;

P(A and B) is calculated by multiplying both probabilities together

P(A and B) = P(A) * P(B)

P(A and B) = 0.3 * 0.7

P(A and B) = 0.21

Hence, P(A and B) = 0.21

Answer:

0.21

Step-by-step explanation:

If A and B are independent, then:

P(A and B) = P(A) × P(B)

Given P(A) = 0.3 and P(B) = 0.7:

P(A and B) = 0.3 × 0.7

P(A and B) = 0.21
