3:30,
4:30,
5:30

<u><em>Explanation:</em></u>
All of the times that end in 30 will fit the criteria because for example 1:30 is 30 minutes after 1:00 and 30 minutes before 2:00. this would hold true for 1 through 12.
If using the military time system you could have 13-24 as well.

Answer:
0.8746 = 87.46% probability of at least 6 failures in 7 trials.
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
7 trials
This means that 
The probability of success in any trial is 9%?
So the probability of a failure is 100 - 9 = 91%, which means that 
Probability of at least 6 failures in 7 trials?
This is:

In which




0.8746 = 87.46% probability of at least 6 failures in 7 trials.
Multiply by cost of a dvd by the number of dvds bought ( x) and add the shipping charge.
A) 33.44 = 9.95x + 3.59
Subtract 3.59 from both sides.
29.85 = 9.95x
Divide both sides by 9.95
X = 29.85/9.95
X = 3
They bought 3 dvds.
B) 33.49-3.59 = 29.85
29.85/9.95 = 3
C) the steps were the same but solving arithmetic you didn’t have to do steps on both sides of an equation.
