Explanation / Answer

22)
Option C)

23)
p = 0.7 , n =140

As per binomial distribution,
P(X=r) = nCr * p^r * (1-p)^(n-r)

P(x = 100) = 140C100 * 0.7^100 * (1-0.7)^40
= 0.0679

Option D)

24)

mean = 200 , s = 50

P(170 < x < 220)

= P((170 - 200)/50) < z < (220-200)/50)
= (-0.6 < z < 0.4)
= 0.3812

Option D)
