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
