Question

Sherane rolls a standard, six-sided number cube. Find p (not composite).

Answer 1

2/3

Explanation:

A six sided number cube :

Sample space = (1, 2, 3, 4, 5, 6)

Non composite numbers on a six sided number cube = (1, 2, 3, 5)

Probability of an event = required outcome / Total possible outcomes

Required outcome = number of non composite numbers = 4

Total possible outcomes = sample space = 6

P(not composite) = 4 / 6 = 2/3
