Calculate each probability, given that p(a) = 0.3, p(b) = 0.7, and a and b are independent. p(a and b)

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

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

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
