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

i really dont know

step-by-step explanation:

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
