7. There are three types of marbles in a bag. There are 12 marbles that weight 0.65g, 9 that weight 0.82g, and 24 that weight 0.5g. Find the mean/expected value of the weight of the marbles. Find the standard deviation for the weight of marbles. If we take 30 marbles from the bag and average their weights, what is the probability of having an average greater than 0.65g?
