a) 3 because the possibility to draw a 3 is 80% and 80%>20%

b) Hint: Find the possibilities by first finding the fraction then convert to a percent to compare.(same thingcfor (c))

expected value is a predicted value of a variable, calculated as the sum of all possible values each multiplied by the probability of its occurrence.
