(NEEDED ASAP) When rolling a die, find the probability of each.

Question

1. P(1 and 4)
2. P(1 or 4)

for #2, i think the answer is 1/3 but I just want to make sure if i’m right or not.

Answer 1

Based on the way the question is phrased, it seems like we are only rolling a single die one time. Therefore, the probability of a single die showing a 1 and a 4 at the same time is 0.

You are correct about part 2. One way to think of it is the following

P(1 or 4) = (Number of desired outcomes) / (Number of total possible outcomes)

P(1 or 4) = 2 / 6 = 1 / 3
