(1) no. of favourable outcome/TOTAL outcome.
no. of favourable outcome =14.
p(e)=14/100.
(2)no. of favourable outcome =89
p(e)=89/100.
no. of favourable outcome =14.
p(e)=14/100.
(2)no. of favourable outcome =89

n[S]=100
1.. no dibisible by 7
={7,14,21,28,35,42,49,56,63,70,77,84,91,98}
n=14
probablity ,=14/100
=7/50
2..number not divisible by 9
100-no. divisible by 9
100-11
=89
