Question

The grocery store received 950 entries for the drawing of a free turkey. If Santa put in 2 entries, what is the probability that he won't win the turkey?

Answer 1

First consider that the probability that Santa wins the turkey is:

p = 2/950 = 1/475

Now, consider that the probability that Santa won't win the turkey is:

1 - p = 1 - 1/475 = 474/475

The probability for Santa won't win the turkey is 474/475
