Answer:
Te correct answer is c) 0.750
Step-by-step explanation:
Lets call:
A = {Allan wins the election}
B = {Barnes wins the election}
MA = {the model predicts that Allan wins}
MB = {the model predicts Barnes wins}
We know that the model has a 50:50 chance of correctly predicting the election winner when there are two candidates. Then:
P(MA | A) = 0.5 = P(MA | B)
P(MB | B) = 0.5 = P(MB | A)
The prior probability P(A) given by the election researcher is 0.75
We must find the posterior probability P(A | MB)
We use Bayes theorem:

We used the result:

Transitive Property (for three segments or angles): If two segments (or angles) are each congruent to a third segment (or angle), then they're congruent to each other. The Transitive Property for three things is illustrated in the above figure. .the Transitive Property for four things is illustrated in the below figure.
