Question

Let a random variable be distributed as shown below

X=x : 0,1,2,3,4,5,6
P(x): .1 .09 .2 .15 .16 .2

(a) Find the probability p(6)
(b) Find the probability P(3< X < 5)
(c) Find the probability P(X < 4)
(d) Find the probability P(X > 2)

Answer 1

P(6) given as .2

P(3<x<5)=Pr(4)=.15
Pr(x>2)=1-Pr(1 or 2or 0)=1-Pr(o)-Pr(1)-Pr(2)
