Answer: The mean for the probability distribution will be 69.25.
Explanation:
Since we given that





As we know the formula for expectation of x i.e. known as mean for the probability distribution,

So, we apply this formula in our case,


Hence, the mean for the probability distribution will be 69.25.
In order to get the answer to this question you will have to find the common factor and then divide the numerator and denominator by the common factor to get the answer.






Therefore the answer is "2."
Hope this helps.
