Anumber cube is rolled 25 times. a number less than four comes up 20 times. what is the experimental probability that a number less than four is rolled?

no not all of them.

step-by-step explanation:

some of them have a square base.

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
