Question

A red die is tossed and then a green die is tossed. What is the probability that the red die shows a number larger than three or the green die shows a number less than three?

Answer 1

Answer:

5/6

Step-by-step explanation:

I'm gonna set up some notation here. I'll use R# to indicate a red die with some number # on it (e.g. R2 for a 2 on the red die, R1 for a 1), and G# for the green die. Since the red die is limited to numbers greater than 3, we can only have the possibilities R4, R5, and R6. The green die is even more limited, with only the possible outcomes G2 and G1.

When we find the probability of this outcome OR the other, we add together their individual probabilities. R4, R5, and R6 represent 3 out of 6 possible rolls for the red die, so the probability of rolling one is 3/6. For the green die, G2 and G1 represent 2 out of 6 possible rolls, giving a probability of 2/6. Adding these two probabilities together, we find that the probability of meeting one of the provided criteria or the other is 3/6 + 2/6 = 5/6.

Answer 2

Answer:

Red: 67%

Green: 33%

Step-by-step explanation:

Since each die has 6 sides, there is a 1/6 chance for every number.

Probability for a number higher than 3 would be 4/6, which is about 67%.

Probability for below 3 would be 2/6, which is about 33%.

I am not 100% sure, but I hope this helps you.
