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

Step-by-step explanation:

The probability that either Jack or Jill will be selected on the first draw is 2/30.

The probability that the other person will be selected on the second draw is 1/29.

The probability of both events is (2/30) (1/29), which simplifies to 1/435.
