Question

# Observe that for a random variable Y takes on values 0 and 1 , the expected value of Y is defined as follows

:

E(Y) = o•Pr(Y=0)+1•Pr(Y=1)

Now suppose that X is Bernoulli random variable with success probability Pr(X=1)=p

Use the information above to answer the following questions

show that E(x4)=p

E(x4)= (.....•p)+(.....•p)=....

1 . Observe that for a random variables
Y takes on values O and I the expected
value of I is defined as follows ,
E ( v = Ox Pr ( Y = 0) + 1 . Pr ( 1 = 1 )
Now suppose that I is Bernoulli random variable
with success probability poolx = 1 ) =p
Use the information above to answer the
following questions
Show that Elx 1=P
