23% adults favor the use of unmanned drones by police agencies. Twelve U.S. adults are randomly selected. Find the probability that the number of U.S. adults who favor the use of unmanned drones by police agencies is(a) exactlythree, (b) at leastfour, (c) less than eight.

P(3)= (round to 3 decimal points)

P(x=>4)= (round to 3 decimal points) equal to or less than 4

P(x<8)= (round to 3 decimal points)
