Step-by-step explanation:

when counting the events we see, he did

22+19+20+18+21 = 100 experiments.

and he got in 20 cases out of the possible 100 a purple marble.

that means the observed probability to pull a purple marble is 20/100 = 1/5.

now he does 25 more pulls.

each with the probity of 1/5 to pull a purple marble.

so, he should expect to pull a purple marble 25×1/5 = 5 times.
