The probabilites fo three events A, B and C are given by P(A) = 0.6, P(B) = 0.4 and P(C) = 0.5 . If `P(AuuB) = 0.8 , P(A nnC) = 0.3 P(Ann BnnC) = 0.2, P(B nn C) = beta` and `P(A uu B uu C) = alpha` where `0.85 le alpha le 0.95` , then `beta` lines in the interval :

A

`[0.35 , 0.36]`

B

`[0.25,0.35]`

C

`[0.20,0.25]`

D
