because its
100-100
---------
     7
which is zero

.The value of p corresponding to zero is 0.5

Freaked12:
part two of Question 3 is also very easy
its states that 33 percent of times are the longest and smallest
so value of p of the middle is 0.34.

1-0.34=0.67
which is +-0.67
(a-100)/7=0.67

will give u the maximum time
(a-100)/7=-0.67
will give you the least time
