- A cell phone salesperson has kept records on the customers who visited his store. Forty percent of the customers who visited the store were female. Furthermore, the data show that 35% of the females who visited his store purchased a cell phone, while 20% of the males who visited his store purchased a cell phone. Let A1 represent the event that a customer is a female, A2 represent the event that a customer is a male, and B represent the event that a customer will purchase a phone.What is the probability that a female customer will purchase a cell phone?I need the answer as soon as possibleIn regular poker where each player is dealt a 5-card hand (no river of sharedcards), what is the probability that you get a two-pair? (A two-pair is a hand with onepair of the same rank, one pair of a different rank, and a single card of a third rank. Forexample, 7 Clubs, 7 Diamonds, 2 Hearts, 2 Spades, K Diamonds.)

- When three athletes compete, the probability of winning the race for the first athlete (A1) is 1/3, the probability for the second athlete (A2) to win the race 1/4, and the probability for the third athlete (A3) to win the race 1/5. Athletes compete 2 times. What is the probability of winning the first race A1 and second race A2, or first race A1 and second race A3?Note: Use the tree diagram. The requested P(A1A2 or A1A3=P(A1A2UA1A3)=P(A1A2)+P(A1A3)Determine whether the eventsare independent or dependent. Then find theprobability.
