Answer:
There will be approx 283908 hits.
Step-by-step explanation:
A website had 342,000 hits in 2011.
This is a decline of 2.3% from the previous year.

Answer:
7 1/15
Step-by-step explanation:
3 2/5 + 3 4/6 = 7 1/15
Part A:
A component is one voter's vote. An outcome is a vote in favour of our candidate.
Since there are 100 voters, we can stimulate the component by using two randon digits from 00 - 99, where the digits 00 - 54 represents a vote for our candidate and the digits 55 - 99 represents a vote for the underdog.
Part B:
A trial is 100 votes. We can stimulate the trial by randomly picking 100 two-digits numbers from 00 - 99. Whoever gets the majority of the votes wins the trial.
Part C:
The response variable is whether the underdog wants to win or not. To calculate the experimental probability, divide the number of trials in which the simulated underdog wins by the total number of trials.
