Explanation / Answer

20 ) probability is always >= 0 and sum of probability should be 1

here sum is 1, bur -1/6 < 0 , which can not be .

hence it is not valid

23) sd = sqrt(E(X^2) - (E(X))^2)

E(X) = 0 +1*0.35 +2*0.10 + 3*0.3 = 1.45

E(X^2) = 0 + 1^2 * 0.35 +2^2 * 0.10 + 3^2 * 030 = 3.45

hence

sd = sqrt(3.45 - 1.45^2)

= 1.16081

hence option A) 1.16 is correct

24 ) E(X) = 0.002 * 1000 + 0.998 * (-5)

= -2.99

25)

option C) is correct

there are 4 suits ,

in binomial there should be 2 different type of outcome

27) P(X =10) =0.0094574

opton C) is correct

27) P(X< 3) =0.2265

option A) is correct
