Question 1038634: The probability that concert tickets are available by telephone is 0.92. For the same event, the probability that tickets are available through a Web site is 0.96. Assume that these two ways to buy tickets are independent. What is the probability that someone who tries to buy tickets both through the Internet and by the telephone will obtain at least one ticket? Round your answer to four decimal places (e.g. 98.7654).
You can put this solution on YOUR website! What is the probability they will fail to get one ticket? That occurs only when they can't get one on the Web and by telephone.
That is 0.08*0.04=0.00032. The probability of getting at least one is the complement, or 0.9968
The other way is probability of both working:0.8832
Getting one (0.96)(0.08)+(0.92)*0.04)=0.1136
That is 0.9968
