. Roll a 6 sided die which is unbalanced so that the probability is 2/9 for each odd number, and the probability is 1/9 for each even number . define a RV X=the number which shows.
a. Find the expectd value of X. (leave as a fraction in lowest terms.)
b. find the variance of X. give the anwer as decimal rounded to the nearest ten-thousandth.
Homework Answers
as P(odd number)=P(X=1)=P(X=3)=P(X=5)=2/9
P(even number)=P(X=2)=P(X=4)=P(X=6)=1/9
a) expectd value of X=10/3
b)
variance of X =2.8889
