Step-by-step explanation:
when we divide a number with 8 remainders is
0 or 1 or 2 or 3 or 4 or 5 or 6 or 7
total number of all possible outcomes = n(S)= 8
no of favourable outcomes= n(E) = 1
probability=P(E) = n(E) /n(S)
= 1/8
the probability of finding the converted decimal number to have 'o' in its units place from the set of No numbers = P(E) = 1/8
