Explanation:
Given
There are three stop codon
TAA, TAG, TGA.
Out of 64 available codons, 3 are stop codon thus the remaining are non-stop codon.
So the probability of choosing a non stop codon is

Let us suppose the number of trials are "x" then the probability of choosing a non stop codon is

Probability of choosing a stop codon is equal to
probability of choosing a non stop codon

Eons into two or more eras, eras into two or more periods, periods into two or more epochs, and epochs into two or more ages.
