Question

From all two-digit numbers with either digit 1,2, or 3 one number is chosen 1) What is the probability of both digits being the same? ii) What is the probability of the sum of the digits being 4?

ANSWER:


11, 12, 13 21, 22, 23 31, 32, 33

i) Total number of numbers formed = 9 Total number of numbers having same digit = 3 Probability of both digits being the same =Total number of numbers having same digit/Total number of numbers formed =3/9=1/3 = 0.33 %3D

ii) Total number of numbers formed = 9 Total number of numbers sum being 4 = 3 Probability of both digits being the same =Total number of numbers sum being 4/ Total number of numbers formed
=3/9=1/3 =0.33
