27 people attend a conference. door prizes are awarded randomly to 2 people. what is the probability that Adam and Samantha will win the door prizes?

Answer 1

Hi Miriam

The probability that either Adam OR Samantha wins the first door prize is 2 chances out of 27.

Assuming that the rules don't allow an attendee to win BOTH prizes, then the probability that the other (Samantha or Adam) wins the second door prize is 1 chance out of 26.

These are separate events, so the total probability is the product of the two transactions.
