To start out, notice that you want the percent of voters that chose candidate A, not the percent of the class that chose candidate A.
Your fraction should be "number that chose candidate A" out of "number of voters," which is the same thing as saying:
"number that chose candidate A" divided by "number of voters"
1) The numerator of the fraction should be the number of votes for candidate A, which is 11.
2) The denominator of the fraction should be the number of voters. You're told that "t<span>here were 11 votes for Candidate A and 15 votes for Candidate B," so there are:
</span>
3) Finally put parts 1 and 2 together into a fraction and multiply by 100 to get your percent. That is your final answer:

The event that either M1 or M2 fails has probability
by the addition rule. Failure events are independent, so
so that
Denote this probability by . Then
follows a geometric distribution with this parameter
and has density
The expectation is .
