Question

There are 1,000 balls in a container. All of the balls are the same size and shape. In the container, there are 400 red balls; 250 orange balls; 100 green balls; and 250 yellow balls. A student will pick one ball at random from the container. What are the probabilities that the student will pick a ball that is either red, orange, or green? Select the three correct probabilities.

A) Red = 1/4

B) Red = 0. 4

C) Orange = 1/4

D) Orange = 0. 4

E) Green = 0. 1%

F) Green = 10%

Answer 1

Red = 400/1000 = 0.4
Orange = 250/1000 = 1/4 [0.25]
Green = 100/1000 = 10%
