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

Answer:

$P(Red) = \frac{3}{20}$

Step-by-step explanation:

Given

$Red = 3$

$Trials = 20$

Required

Determine the experimental probability of next marble being red

This is calculated as:

$P(Red) = \frac{n(Red)}{Trials}$

Substitute values for n(Red) and Trials

$P(Red) = \frac{3}{20}$
