Best ResponseYou've already chosen the best response.0if she misses her first serve, her second serve goes in 90% of the time. whe this happens, she wins the point on her second serve 35% of the time. find the probability that venus wins a point when she is serving.

Best ResponseYou've already chosen the best response.0\[p(wp)=p(wpGs1).P(Gs1)+p(wpGs2).P(Gs2)\]

Best ResponseYou've already chosen the best response.0what i would do would be: \[.75*.80 + (1  .75*.80)*.9*.35\] the first part being the probability of her winning her first serve and the second of her winning her second serve given a result of her first serve. again its been forever since I've done any probability

Best ResponseYou've already chosen the best response.0So, i) She could either get her first serve in and get a point (0.75 * 0.80) ii) She could else get her first serve wrong, second serve right and point on her second serve ( 0.25 * 0.90 * 0.35) Sum up i) and ii) 0.6 + 0.079 That's 67.9% , same as what you got! So guess its right! :D
