coffee or orange juice. There were 30 customers who bought orange juice
and 40 customers who bought coffee. What is the probability that a
randomly selected customer bought both coffee and orange juice?
Express the answer as a decimal rounded to the nearest hundredth. *

There were 25 students who answered to a survey about sports. four-fifths of them like football. how many students like football?

How can i differentiate this equation?

Our star pitcher, foster enlight, can throw a pitch so fast that it gets to the catcher’s mitt before it leaves foster’s fingers! if the team wins a game then the probability that foster was pitching is 0.8 but only if foster had at least one day’s rest since his last pitching assignment. if foster does not have a day off and the team still wins, the probability that foster was pitching drops by half of what it was on the previous day. if the team wins three games in succession from the toronto tachyons and foster pitched in game #2, what is the probability that he pitched in one or more of the other games? (assume that foster did not pitch on the day before the first game of this three game series.)
