Question

Suppose you choose a marble from a bag containing 2 red marbles, 5 white marbles, and 3 blue marbles. You return the first marble to the bag and then choose again. Find P(red and blue).

Answer 1

P(red) = (number of red marbles)/(total number of marbles)

P(blue) = (number of blue marbles)/(total number of marbles)

P(red) = P(red) * P(blue)
