Question

You randomly draw a marble from a bag, record its color, and then replace it. You draw a red marble 3 out of 20 times. What is the experimental

probability that the next marble will be red?

Answer 1

`P(Red) = (3)/(20)`

Explanation:

Given

`Red = 3`

`Trials = 20`

Required

Determine the experimental probability of next marble being red

This is calculated as:

`P(Red) = (n(Red))/(Trials)`

Substitute values for n(Red) and Trials

`P(Red) = (3)/(20)`
