A line of trucks has two types of holdup. We estimate that 4% of holdups are due to signal light errors and 3% due to batteries. 4% of the trucks are experiencing exclusively one of these holdups. A truck in the lineup is randomnly selected.

a) what is the probability that it has both types of holdups?

b) What is the probability that it has none of these holdups?

If 5 coins are tossed, what is the probability of getting 5 Tails? Select one: a. 1/32 b. 1/10 c. 1/16 d. 1/8 A flashlight has 6 batteries, two of which are defective. If two batteries are selected at random without replacement, find the probability that both are defective. Select one: a. (4/6)*(3/5) = 12/30 = 0.40 b. (1/6)*(1/6) = 1/36 = 0.028 c. (2/6)*(2/6) = 4/36 = 0.111 d. (2/6)*(1/5) = 2/30 = 0.067

An urn has 12 balls. 8 are white balls and 4 are black balls. If we draw a sample of 3 balls (i.e., picking without replacement) and given that the first two balls selected were a black ball and a white ball, what is the conditional probability of the third ball drawn being white?

Suppose there are a two different types of travellers. The safe ones and the unsafe ones. No matter the type of travellers, they all own $20,000 in the good state of the world. If they get into an accident while travelling they lose $15,000. The utility of a traveller is u(y)= y^(1/2) . Consider the competitive market for travel insurance in answering the following questions. Whenever I refer to the state contingent space, put money in the good state on...
