You roll a 6-sided die two times. What is the probability of rolling a 4 and then rolling a number less than 6?

AZ:

A six sided die has six sides What's the probability of getting a 4? There's only one side that has a 4

AZ:

And then we also want to know the probability of getting a number less than 6 How many numbers are there less than 6? There's 1, 2, 3, 4, and 5 so what's the probability of getting a number less than 6?

AZ:

so the probability of getting a 4 AND then getting a number less than 6 is going to be probability of getting 4 * probability of getting a number less than 6
