Answer:
0.128 is the probability that the third hole drilled is the first to yield a productive well.
Step-by-step explanation:
We are given the following information in the question:
The probability that he is successful on a given trial is 0.2
p = 0.2
q = 1 - p = 0.8
We define the geometric probability as:
For this we have x = 3, putting the values we have:
0.128 is the probability that the third hole drilled is the first to yield a productive well.

Answer:
F) 75
Step-by-step explanation:
Use the Pythagorean theorem: a^2 + b^2 = c^2
a = 21
b = 72
c = length of BC
21^2 + 72^2 = c^2
5625 = c^2
c = 75
