Suppose 70% of kids who visit a doctor have a fever, and 45% of kids with a fever have sore throats. What's the probability that a kid who goes to the doctor has a fever and a sore throat?I am stuck on this question, sadly I just did a lot of these for my exams but I forget how to solve it. Someone help??
Answers
To find the probability that a kid has both a fever and a sore throat, multiply the two probabilities together: 70% * 45% = 31.5%
70/100 = 0.7% 45/100 = 0.45% 0.7 x 0.45 = 0.31 0.31= 31% 31% is your answer sir
