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
