Aspinner is divided into two equal parts, one red and one blue. the set of possible outcomes when the spinner is spun twice is s = {rr, rb, br, bb}. let x represent the number of times blue occurs. which of the following is the probability distribution, px(x)?

Step-by-step explanation:

Given that a spinner is divided into two equal parts, one red and one blue.

When the spinner is spun twice, X, the number of times blue occurs can take values as 0,1,2

I.e. either no blue occurs or 1 blue occurs or 2 blue occurs.

P(X=0) = P(RR) = 0.25

P(X=1) = P(RB, BR) = 0.5

P(X=2) = P(BB) =0.25

other wise prob =0

The above is the probability distribution of number of blues

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile
