Question

A bag of 100 marbles contains an equal amount of marbles that are blue, green, red, yellow, and orange. If one marble is pulled at random from the bag, the probability that it is a green marble is

Answer 1

The probability of drawing a green marble from the bag can be calculated as the number of green marbles over the total number of marbles in the bag. Since there are an equal amount of each color marble in the bag, there are 100/5 = 20 marbles of each color. Therefore, there are 20 green marbles in the bag.

The probability of pulling a green marble is the number of green marbles (20) divided by the total number of marbles (100):

P(green marble) = 20/100 = 0.2 = 20%

Therefore, the probability of pulling a green marble from the bag is 20%.
