A bag contains 9 purple, 3 blue, 6 black, 2 orange, and 4 gray marbles. (Leave solution as a simplified fraction).
What's the probability of randomly selecting a blue marble, without replacing it, and then selecting a blue marble?

Explain step-by-step how to simplify -5(2x – 3y + 6z – 10).

Abag contains 3 red marbles, 2 blue marbles, and 2 green marbles. one marble is picked, then another marble. assume that the selections are made with replacement. a) find the probability of picking two red marbles with replacement. b) find the probability of picking a red marble and a blue marble. assume the selections are made without replacement. c) find the probability of picking two red marbles without replacement. d) find the probability of picking a red marble and a blue marble without replacement.
