Answer:
Step-by-step explanation:
Given : A spinner has five equal parts labeled from 1 to 5.
The spinner is spun twice.
To Find: What is the probability of getting a 4 twice in a row?
Solution:
Numbers on spinner = {1,2,3,4,5}=5
Favorable outcome = {4}=1
So, probability of getting 4 on first spin =
Now probability of getting 4 on second spin =
So, the probability of getting a 4 twice in a row =
=
Hence the probability of getting a 4 twice in a row is

If we plot that point we find ourselves in QIV. The distance along the x axis is 4, and the distance down from that point is -3. If we create a right triangle with that segment, that segment serves as the hypotenuse of the triangle. We need its measure. Using Pythagorean's theorem, 
and 
. We see that c = 5. We need now to find the secant of that right triangle. Secant if the co-identity of cosine which is side adjacent over hypotenuse. That means that secant is the hypotenuse over the side adjacent. So our secant theta = 5/4
