An appliance dealer sells three different models of freezers having 13.5, 15.9 and 19.1 cubic feet of storage space, respectively. The percentages of sales of freezers of the above sizes were 20%, 50%, and 30% respectively.
Let ?W be the amount of storage space of the freezer purchased by the next customer to buy a freezer.
Find the probability mass function of W is W discrete or continuous?
The profits from each of the above freezers are Rs. 1000, 1200 and 1600 respectively. If two freezers are sold per day, what is the probability that the total profit per day will be greater than Rs 2500?
