@Kameron018 can you help me

Answer 4

When rolling a single die there are 6 possible outcomes: 1, 2, 3, 4, 5 or 6.
Find the probability that the number rolled is AT LEAST A 4.
We are interested in the outcomes: 4, 5 and 6.
Three out of 6 possibilities. So the probability is 3/6 = 1/2.

This is the theoretical probability.
