Question

Mandy performed an experiment in which she randomly drew one marble at a time from a bag, with replacement. The bag contained one marble each of red, blue, green, yellow, and purple. The results of her experiment are shown below. Marble Color Times Drawn red 5 blue 7 green 7 yellow 3 purple 8 Based on the experiment above, predict the number of times a yellow marble would be drawn if she performs the experiment a total of 90 times.

Answer 1

Answer: 9

Step-by-step explanation:

Results in the experiment:

Marble Color   Times Drawn

 red                      5

blue                       7

green                       7

yellow                       3

purple                       8

Total marbles = 5+7+7+3+8 = 30

Probability of getting yellow marble = $\dfrac3{30}=\dfrac1{10}$

If she performs the experiment a total of 90 times= $\dfrac{1}{10}\times90=9$.

Hence, the number of times a yellow marble would be drawn = 9
