Question

please solve this question

Answer 1

Total outcomes = 90

1. Favorable outcomes = 90 - 9 = 81
Probablity = 81/90
= 9/10

2. Favorable outcomes = 9 {1,4,9,16,25,36,49,64,81}
Probablity = 9/90
= 1/10

3. Favorable outcomes = 90/5 = 18
Probablity = 18/90
= 1/5

Answer 2

HEYA DUDE...!!!

NO.of possible outcomes = 90

FORMULA : P(E)=NO.of Favourable outcome/total no.of outcomes

(i).Favourable outcomes = 81
P(E)=81/90
(ii).Favourable out.=9
P(E)=9/90
(iii).Favourable out.=18
P(E)=18/90
