Question

A bag holds 2 yellow, 1 green, and 2 red marbles. if you were to draw a marble from the bag 150 times, and replace it after each draw, how many yellow marbles would you expect to draw?

Answer 1

A bag holds 2 yellow, 1 green, and 2 red marbles. if you were to draw a marble from the bag 150 times

Bag holds 5 marbles. There are 2 yellow marbles

Probability (event) =
`(number of times occur)/(total number)`

So probability (picking yellow ) =
`(2)/(5)`

Yellow marbles expect to draw =
`(2)/(5) * 150 = 60`
