Answer:
Incomplete question, but you can use the formulas given to solve it.
Step-by-step explanation:
Uniform probability distribution:
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:

The probability of finding a value between c and d is:

The probability of finding a value above x is:

Uniform distribution over an interval from 0 to 0.5 milliseconds
This means that 
Determine the probability that the interarrival time between two particles will be:
Considering
, and the question asked, you choose one of the three formulas above.
His sister is 7.895 feet tall.
1 km = 1,000 m....so 322km = 322,000 m
so the falcon can fly 322,000 m per hr
With
, we have

Since
, we can further write this as
