2 3/4 weeks because 2 a week then another week is 4 then add a 1/2 because it’s 5 then add a 4th because there’s another 1/2 so you get 2 and 3/4 weeks
Using the binomial distribution, there is a 0.0874 = 8.74% probability that not enough seats will be available.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
For this problem, the values of the parameters are given by:
n = 15, p = 0.85.
The probability that not enough seats will be available is P(X = 15), as the only outcome in which not enough seats will be available is when all 15 people who bought the ticket show up, hence:


0.0874 = 8.74% probability that not enough seats will be available.

Answer:
55/77
Step-by-step explanation:
The sum of the numbers in the given fraction is 5+7=12. The sum 132 is 11 times that value. Multiplying 5/7 by (11/11) will give the fraction you want:
(5/7)×(11/11) = 55/77 = 5/7
