Probability, logic and sampling

Five draws are made at random with replacement from the follwing box (which has 5 tickets). 1 (a) Find the probability that the sum of the draws is 5. (b) Find the probability that the sum of the draws is 4. (c) From the histogram for the sum of draws, draw the blocks for 4 and 5. (d) Find the expected value for the sum of the draws. (e) True or false. i. The standard error for the sum of the draws is = V10. ii. Since the histogram for the sum of draws has a left tail, the median sum of draws is less than th average. (The median of a histogram is the point on the horizontal axis with 50% of the area below and 50% above.)
