A certain tennis player makes a successful first serve 77% of the time. Assume that each serve is independent of the others. If she serves 4 times, what's the probability she gets a) all 4 serves in? b) exactly 2 serves in? c) at least 2 serves in? d) no more than 3 serves in?
A certain tennis player makes a successful first serve 62% of the time. Assume that each serve is independent of the others. If she serves 6 times, what's the probability she gets a) all 6 serves in? b) exactly 5 serves in? c) at least 4 serves in? d) no more than 3 serves in? a) The probability that she gets all 6 serves in is nothing.
14. A certain tennis player makes a successful first serve 72% of the time. Assume that each serve is independent of the others. If she serves 7 times, what's the probability she gets a) all 7 serves in? b) exactly 6 serves in? c) at least 5 serves in? d) no more than 6 serves in? (Round to three decimal places as needed.).

Find the indicated Probability. Show work. A tennis player makes a successful first serve 51% of the time. If she serves 9times, what is the probability that she gets exactly 3 first serves in? Assumethat each serve is independent of the others.
The average first serve of a certain tennis player follows a symmetrical, mound-shaped distribution with a mean of 122 and a standard deviation of 6.2 (miles per hour). Based on this information, approximately 95% of the first serves will fall between 115.8 and 128.2. True False
A player serving in tennis has two chances to get a serve into play. If the first serve is out, the player serves again. If the second serve is also out, the player loses the point. Observe the probabilities based on four years of the Wimbledon Championship P(1st serve in) = 0.59 P(win point 1st serve in) = 0.73 P(2nd serve in |1st serve out) = 0.86 P(win point | 1st serve out and 2nd serve in) = 0.59 Make...
