Question

a computer is programmed to generate a sequence of three digits, where each digit is either 0 or 1, and each of these is equally likely to occur. construct a sample space that shows all possible three-digit sequences of 0s and 1s and then find the probability that a sequence will contain at least one 0.

Answer 1

A.

Explanation:

Answer 2

Sample space:

000
001
010
011
100
101
110
111

From the sample space, total = 8

At least one 0, there are 7 with at least one 0

Probability = Possible outcome / Total = 7/8
