What array, I don't see anything.
Using the uniform distribution, we have that:
a) The density curve is given at the end of this question.
b) 16.67% of the time does a customer have to wait between 100 and 120 seconds.
-----------------
The uniform distribution has two bounds, a and b, and the probability of finding a value between c and d is given by:
- Uniform distribution on the interval of 0 to 120 seconds, thus .
The proportion between 100 and 120 seconds is:
0.1667*100% = 16.67%
16.67% of the time does a customer have to wait between 100 and 120 seconds.

Answer: Third quartile =$21.58
Step-by-step explanation:
Let x be value of a stock .
For uniform distribution,
probability density function =
Let a be the stock value such that P(x<a) =75% or 0.75
Hence, 75% of all days the stock is below $21.58 or Third quartile =$21.58 .
