Suppose you have an equal sided spinner that is numbered 1 thru 5 and another spinner with 4 equal sections with the colors red, blue, yellow and green. What is the P (spinning a number less than 4 and landing on red)? *

3/20

First you find the probability of spinning a number less than 4. This does not include 4 as it does not say less than it equal to. There are 3 numbers less than 4 and there are 5 numbers in total so your probability here is 3/5.

Then, you find the probability of it landing on red. There are 4 sections and red is 1 of them, meaning the probability of this is 1/4.

When finding the probability that two things both happened, you need to multiply these together.

3/5 x 1/4 = 3/20, so I think your answer is 3/20.

I did get a little confused myself over whether it would be 3/4 or 1/4 but came to the conclusion it would be 1/4. Thought I’d let you know just in case.

I hope this helps :)

Y=3x+1 so the first one
