Question

Suppose an experiment consists of randomly drawing a marble out of a bag and replacing the marble. the bag contains 3 yellow marbles, 4 red marbles, and 8 blue marbles. if the experiment were repeated 20 times, how many times would you predict the chosen marble would be yellow?

Answer 1

Hi there!

Since the yellow marbles to the radio of total marbles is 3/15,

3/15 = 5

We need to divide the total amount is times the marble is drawn by the ratio.

20 ÷ 5 = 4

So, the yellow marble would be drawn 4 times.

Hope this helps!

Answer 2

P=3/(3+4+8)=3/15=1/5
after 20 times it can be (1/5)*20=4 times
