Solution
The correct option is C 14/100
Number of terms in sample space{n(S)} = 100 E(number divisible by '7' in sample space) = 7,14,21,28,35,42,49,56,63,70,77,84.91.98. Number of terms in E {n(E)} = 14Therefore, P(getting E) = n(E) /n(S) = 14/100
Number of terms in sample space{n(S)} = 100
E(number divisible by '7' in sample space) = 7,14,21,28,35,42,49,56,63,70,77,84.91.98.
Number of terms in E {n(E)} = 14
Therefore, P(getting E) = n(E) /n(S)
= 14/100
