Answer:  Probability that an athlete uses steroids given that he tests positive is 91.6%.

Step-by-step explanation:

Let A be the event that athletes test positive for steroids .

Let B be the event that he actually use steroids.

Since we have given that

Probability that athletes test positive for steroids = P(A) = 12%

Probability that athletes test positive for steroids and actually use steroids = P(A∩B) = 11%

So, we need to find the probability that an athletes use steroids given that he tests positive.

For this we will use "Conditional probability":

P(B\mid A)=\dfrac{P(A\cap B)}{P(A)}\\\\P(B\mid A)=\dfrac{11}{12}\\\\P(B\mid A)=0.916\\\\P(B\mid A)=0.916\times 100\%\\\\P(B\mid A)=91.6\%

Hence, Probability that an athlete uses steroids given that he tests positive is 91.6%.
