well, we'll be using the distance formula twice here.
that point, is on the x-axis, what's the value of "y" at the x-axis? well y = 0, since it's way down at the 0 level, so the point must be (x , 0).
the distance then from (x,0) to (-3,-1) is the same distance as from (x,0) to 1,6).

This is a binomial distribution.
p = 0.71, q = 1 - p = 1 - 0.71 = 0.29, n = 20
P(x ≤ 19) =1 - P(x = 20) = 1- 20C20 x (0.71)^(20 - 20) x (0.29)^20 = 1 - 0.29^20 = 1 - 0 = 1
