C. 3/5
The definition of terminating decimal is that it’s an answer that come to an end after a few decimal places. When looking at a b and d their denominators are 7 and 3 which will give answers with a never ending amount of decimals. This makes them nonterminal decimals. So the answer is c because it has a decimal place and it can give a final answer
Expected value = Sum of Probability * Cost of each ice cream.
Expected value
= 50%* $1.20 + 30%* $2.00 + 2<span>0%* $3.50
</span>
= 0.50* $1.20 + 0.30* $2.00 + 0.2<span>0* $3.50
</span>
= $1.90
Expected value of the cost of one ice cream = $1.90
