a) Determine the value of the distribution
function at point x = 6.
b) Determine the expected value.
Example 2
Calculate the expected value of the continuous
random variable with the density function
for 
= 0 otherwise
Example 3
A certain
party received 25% of the votes in an election. Determine the probability that among
the 10 voters addressed there will be no more than 4 voters of that party.
