7 (i) 3(1/6) = 0.5
(ii) 9- 1/30 10-3/10 11- 0.5 12- 1/6 ( sum = 1)
(iii) not independent P(R) x P(S) = 1/5 which is not euqal to P(SnR) = 1/6
(iV) not mutually exclusive P(SnR) = 1/6 ( not 0)

 

[moinul]

[moinul]

7)ii) how did u solved man...

[Arham93]

stepping question??..the continous correction one??

 

[urvi kapoor]

Yes

 

[Arham93]

well since inclusive was written and the probabilities were given i used np and npq to solve the question with using +.5 on the starting value and -0.5 on the ending vaule rest was easy..

 

[moinul]
