Suppose an experiment consists of randomly drawing a marble out of a bag and replacing the marble. the bag contains 3 yellow mar
bles, 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?
2 answers:
P=3/(3+4+8)=3/15=1/5
after 20 times it can be (1/5)*20=4 times
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!
