Step-by-step explanation:
-This questions needs as to determine the probability of scores less than 282 then find the expectation;
-Let X be the score of a random selection:


The probability of scores below 282 is 0.84134 or 84.134%
Hence, 84.134% of the scores were below 282
<em><u>The solution is:</u></em>

<em><u>Solution:</u></em>
We have to solve the given expression
<em><u>Given expression is:</u></em>

<em><u>Let us first convert the mixed fraction to improper fraction</u></em>
Multiply the whole number part by the fraction's denominator.
Add that to the numerator.
Then write the result on top of the denominator.
Thus we get,


<em><u>Thus the given expression becomes,</u></em>

Make the denominators same for easier calculations

<em><u>Reducing to lowest terms, we get</u></em>

<em><u>In decimal form, we get</u></em>

<em><u>Thus the solution is:</u></em>
