Using the image above, what is the theoretical probability of picking a yellow counter in simplest form? _____
A.30%
B. 50%
C. 70%
D.100%
Joan picks a random counter out of the bag 10 times, and she got a yellow counter 7 times. What is the experimental probability of picking a yellow? ____
A.30 %
B.50%
C. 70 %
D. 100%
The theoretical probability of picking a yellow counter is 70% (C).
The experimental probability of picking a yellow counter is calculated by taking the number of times Joan picked a yellow counter (7) and dividing it by the total number of times she picked a counter (10).
7/10 = 0.7 = 70%
So, the experimental probability of picking a yellow counter is 70% (C).
