Give the mean of the following probability distribution? number of song requests (x) P(x) 0.21 0.31 0.16 0.14 0.18 8 9 10 11 12 Using the multinomial formula, find the probability of the following data. n=17, x₁ = 8, x₂ = 5, x3 = 4 P₁ = 0.58, P₂ = 0.25, p = 0.17 Suppose that only 20% of all drivers come to a complete stop at an intersection having flashing lights in all directions when no other cars are visible. What is the probability that, of 10 randomly chosen drivers coming to an intersection under these conditions, a) At most 4 will come to a complete stop? b) Exactly 4 will come to a complete stop? c) At least 4 will come to a complete stop? d) How many of next 20 drivers do you expect to come to complete stop?
