Question

There are 30 names in a hat. If two names are picked without replacement, which expression shows the probability that Jack and Jill will be picked?​

Answer 1

Answer: Choice C)

(1/30)*(1/29)

Explanation:

Jack has a 1/30 chance of being picked since he is 1 person out of 30 total. After his name is picked, and not put back, there are 30-1 = 29 names left. The chances Jill is picked is 1/29. The two fractions are multiplied to get the overall probability both are picked.
