just form a simulation model

Lt/view?usp=sharing B. In August, a book store must decide how many of next year's nature calendars to order. Each calendar costs 7.50 and sold for 10.00. After Feb 1 all unsold calendars will be returned to the publisher for a refund of 2.50/calendar. The book store estimates that the number of calendars it can sell by Feb 1 follows the following probability distribution. The book store wants to develop a simulation model to decide how many calendars to order. Take 10 Random numbers for the simulation. Probability 0.3 Calendar Demand 100 150 200 0.20 0.30 250 300 0.15 0.05
