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

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
