Question

A student is equally likely to select pizza, nachos or, chicken for lunch. what is the probability the student DOES NOT select chicken?

1/3, 1/2, 1/3 or 1?

Answer 1

Since the student is equally likely to select pizza, nachos, or chicken for lunch, the probability of selecting each of these options is 1/3.

The probability that the student does not select chicken is the probability of selecting pizza or nachos, which are the two options other than chicken. Since these two options are equally likely, the probability of selecting pizza or nachos is 1/2.

Therefore, the probability that the student does not select chicken is 1/2.
