Marked out of 1) The numerical value of the probability of a particular outcome is 39.00 2) Outcomes are 3) The list of outcomes is Part 2 This following data is the number of paintings sold per day by an artist, Jo, over the past week. 2 Complete the discrete probability distribution below: Number of Probability Frequency paintings P(x) sold (x) 0 2 3 What is the mean number of paintings sold? What is the variance in the number of paintings sold? Is the above situation a binominal probability distribution? Part 3 At Jo's art collective, all of the artists sell on weekends. 70% of artists sell their work only on the weekend. The remaining 30% of the artists also sell their work on weekdays. Suppose Jo chooses a random sample of 4 other artists to talk to. a) Does this situation fit the assumptions of the binomial distribution? b) What is the probability that none of those artists sell on weekdays? c) What is the probability that more than 2 of those artists sell on weekdays?

Part 4 If 100 artists are invited to sell at a market on a Wednesday, what is the probability that at least 26 will be interested?
