Question

Steve has a 20-sided die with numbers from 1 to 20. What is the probability that Steve rolls a number that is 5 or below?

Answer 1

We have that the probability per side is 1/20

we have that the numbers are 5 or below 5 so it can be 5,4,3,2,1

`P=(1)/(20)+(1)/(20)+(1)/(20)+(1)/(20)+(1)/(20)`

then we sum

`P=(5)/(20)=(1)/(4)`

the probability is 1/4
