Question 11

Cars
 Suppose X = the number of cars owned by a family in the U.S.The probability distribution of X is shown in the table below.  ​ ​
-{Cars Narrative} Suppose you choose two families at random.What is the chance that they each own one car? (That means family A owns a car and family B owns a car.)

Accepted Answer

The probability that each of two independent events happens is the product of their individual probabilities. If the probability that one family owns a car is 0.23, then the probability that both family A and family B each own a car is (0.23)*(0.23) = 0.0529.

Question 16

If P(A)= 0.25 and P(B)= 0.65,then P(A and B)is:

Accepted Answer

The probability of A and B occurring together (P(A and B)) depends on whether events A and B are independent, mutually exclusive, or neither. Without information on the relationship between A and B, we cannot determine P(A and B) from just P(A) and P(B).
