Experimental Probability-Instruction-Level G
Mariana chooses a golf ball from a bucket at random, notes the color, and puts it back. After several
trials, she finds that she chose a yellow golf ball 8 times. Based on this, she predicts that if she
chooses a golf ball from the bucket 240 times, 160 will be yellow.
How many times did Mariana choose a golf ball
from the bucket?
12 times
Mariana chooses a golf ball from the bucket at
random 4 more times and none of the golf balls
are yellow. What is the experimental probability
of choosing a yellow golf ball based on all of
Mariana's trials?
