Find the cumulative distribution function of X and draw itsgraph?
A salesman has scheduled two appointments to sell encyclopedias.His first appointment will lead to a sale with probability 0.3, andhis second appointment will lead independently to a sale withprobability 0.6. Any sale made is equally likely to be either forthe deluxe model, which costs $1000, or the standard model, whichcosts $500. X is the total dollar value of all sales. Hint: youcould find the probability mass function of X and use that.
