Question

A bag of marbles contains 5 blue marbles, 3 green marbles, and 2 purple marbles. What is the probability of drawing a green marble, removing it, and then drawing a blue marble?

Answer 1

The probability of drawing a green marble is

P (green) = number of green marbles / total number of marbles in the bag.

Use the given information and find the value of P (green).

Since you are not putting back the green marble in the bag,

P (blue) = (number of blue marbles / Total number of marbles in the bag – 1)

Now, to calculate the probability of the successive events you must multiply P(green) and P (blue).

If you have to keep your answer in the fraction form, remember to keep it in lowest terms.
