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
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
