Question 359643: I am trying to understand the probability notation. I can do the math and figure the answer, but can't get the probability notation right.
Questions is: During the winter months I have two cars that are hard to start. 1990 mustang and a 1993 ranger. The probability that my mustang will start is .08 and the ranger is .03. Let A represent the mustang starts, and B represent the ranger starts event. Use the probability notation and solve the following.
A. What is the possibility that I can start at least one car?
B. What is the probability that I cannot start either car?
Thanks,
Brian

You can put this solution on YOUR website! During the winter months I have two cars that are hard to start. 1990 mustang and a 1993 ranger. The probability that my mustang will start is .08 and the ranger is .03. Let A represent the mustang starts, and B represent the ranger starts event. Use the probability notation and solve the following.
A. What is the possibility that I can start at least one car?
---
P(at least one) = 1 - P(start neither)
---
P(start at least one) = 1 - 0.92*0.97 = 1 - 0.8924 = = 0.1076
-----
B. What is the probability that I cannot start either car?
P(start neither) = 0.92*0.97 = 0.8924
