Question

If pn = 15 and qn = 45,what is the value for p?​
A)​p = 1/3
B)​p = 0.30
C)​p = 1/4
D)​p = 4.0

Quizplus · Accepted Answer

We know that pn = 15 and qn = 45. Since p + q = 1, we can solve for q: 
q = 1 - p
Substituting qn = 45, we get: 
45 = (1 - p) * 15
Dividing both sides by 15 and simplifying, we get: 
3 = 1 - p
p = 1 - 3
p = -2
However, we know that p is a probability and therefore must be between 0 and 1. Therefore, the only possible choice is C) p = 1/4, which is a valid probability that satisfies the given conditions.
