Suppose 70% kid who visit doctor have fever & 15% kid has fever + sore throat. What probability that kids who goes to doctor has fever + sore throat

Question

mathmale · Answer

You might want to begin by expressing the probabilities mathematically:
If '70% of kids who visit a doctor have a fever,' then P(kid has fever) = 0.70.

Please write out the other given probability, using the same format.

We could shorten that to P(F)=0.70.
P(T)=?

Our goal in this problem is to find P(F  AND  T).  In other words, we're looking for the probability that two medical problems will be found occurring simultaneously.  The mathematical name for that is "intersection."

What's the formula for the probability of two independent events occurring simultaneously, given the probability of each one happening individually?
