Can anyone help me answer these questions soon as possible?

9.2 Theoretical and Experimental Probability:

Situation: a dice is being rolled.

In theory think about how many sides are on a dice and the numbers that are shown on each side.

In an experiment the dice is rolled 20 times and lands on 1 two times and on 5 four times.

Find each experimental and theoretical probability.

landing on 5

experimental ?
theoretical ?

Answer 1

landing on 1

experimental = 2/20 = 1/10
theoretical = 1/6


not landing on 1

experimental = 1 - 1/10 = 9/10
theoretical = 1 - 1/6 = 5/6

landing on 5

experimental = 4/20 = 1/5
theoretical = 1/6
