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.
