(a) What is the probability of not getting any hits in a game?(b) What is the probability of getting three hits in a game?(c) What is the probability of getting at least one hit in a game?
I was recently told that I tested positive for a rare (only affects 1 in 10,000 people) and fatal disease (no known cure or treatment). When we were told the news, my wife was devastated - me, not so much. I asked the doctor how accurate the test is. He indicated it is 98% accurate - when you have the disease, the test is positive 98% of the time and when you do not have the disease, the test is negative 98% of the time. Calculate the probability I have the disease given I have tested positive forthe disease (hint: the answer is NOT 98%).
