The experimental probability that Alexander wins a tennis match is 0.21. If he plays 40 tennis matches in the next week, about how many matches can Alexander expect to lose? Is it 32 matches?

Jason remembers nine digits of a ten digit phone number. He remembers that the last digit is an even number. If he guesses that last digit, what is the probability that he dials the correct number? My answer: 1/5 probability

The experimental probability that Mindy will win a game of chance is 2/5. The experimental probability that James will win the game of chance is 5/8. If they each play 200 games, who will win more games and by how much? work: I made 2 proportions 2/5 = x/...

how do I do it then?

thank you!

fyi this is actually right Assuming 0 counts as an even digit, then the last digit must be 2, 4, 6, 8, 0 = 5 options Only one of these is the correct one Therefore the probability that he dials correctly = 1/5 or 0.20 or 20%
