yellow, green, purple, and black). She randomly chooses two folders to use for

her first two classes. What is the probability that her first choice is red and her

second choice is blue?

Marilyn Johns · Answer 1

The sample space is 6 different colors

1) P (Red) = 1/6 P (Blue) = 1/6

P (Red AND Blue) = P (Red ∩ Blue) (1/6) x (1/6) = 1/36

2) P (of Blue) = 1/2, P) Red) = 1/2, P (getting 5) = 1/6, P (getting 1,2 or 3) = 3/6=1/2

P (Blue AND 5) = 1/2 x 1/6 = 1/12

P (Red AND 1 OR 2 OR 3) = 1/2 x 1/2 = 1/4

Probability of Event A AND Event B = 1/12 x 1/4 = 1/48 = 0.021 (I don't see it on your paper)

3) Probability of getting 1 Ace = 4/52

The probability of getting another ace will be 3/51 (since 1 ace was drawn & 3 are remaining. Also the number of cards from 52 to 51)

4/52 x 3/51 = 12/2652 = 1/221
