To the right are the outcomes that are possible when a couple has three children. Assume that boys and girls are equally​ likely, so that the eight simple events are equally likely. Find the probability that when a couple has three​ children, there is exactly 1 girl.   1st   2nd   3rd   boy − boy − boy   boy − boy − girl   boy − girl − boy   boy − girl − girl   girl − boy − boy   girl − boy − girl   girl − girl − boy   girl − girl − girl   What is the probability of exactly 1 girl out of three​ children?   _____________ ​(Type an integer or a simplified​ fraction.)

You enrolled in a biology class and don’t know yet which Biology Professor and Biology Laboratory Assistant you will get. You like Professor Smith (Biology Professor), but the professor will be randomly selected from a group of 10 professors. You also like Ms. Jones, who is one of 5 Biology Laboratory Assistants. Laboratory Assistants are also randomly selected for classes. The probability of getting both Professor Smith and Ms. Jones for the same biology class = 1/50. What is the probability that you will get at least one of your instructor preferences (Professor Smith or Ms. Jones)?

The Dallas Mavericks play the Oklahoma City Thunder in a best of 7 game NBA playoff series. If the probability that the Mavs beat the Thunders is 40% for each game, what is the probability that Dallas wins the series(first to win four games) in at most 7 games?

The average number of times per week that John's 3 dogs wake him up at night because the dogs want to play is ten. We are interested in the number of times his dogs wake him up each week. Find the probability that the three dogs will wake John up no more than five times next week
