Answer:
2/3
Step-by-step 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
