Step-by-step explanation:

Given

There are four options to multiple choice question and only one is correct which will reward 5 points.

Using Binomial distribution to get the result since no of trials is finite

n=5

chances of guessing a correct question p=0.25

and mean for Binomial distribution is given by

$\mu =np$

$\mu =5\times 0.25=1.25$
