The expected score that Joe can obtain provided the probability of the left-out questions being correct as per the given situation is 90.8.
Points secured by Joe by answering correctly = 12*6 = 72
Probability is the conversion of possibilities or occurrences in numbers.
Now, the probability of a correct guess in the questions in which Joe eliminated 2 choices = 1/3
So, the possible marks of Joe in those 4 questions = 1/3*4*6=8
Probability of correct guess in remaining 9 random guesses= 1/5
So, the possible marks that Joe can score in those 9 random guesses = 1/5*9*6 = 10.8
Therefore, the expected score of Joe = 72+8+10.8 = 90.8
