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%.

Answer:

  • Graph B

Step-by-step explanation:

<u>According to data in the table we see pairs of points:</u>

  • (3, 75), (5, 125)

<u>This gives us the rate of change:</u>

  • (125 - 75)/(5 - 3) = 50/2 = 25

<u>The y - intercept is zero:</u>

  • 75 = 3*25 + b
  • 75 = 75 + b
  • b = 0

<u>The line is:</u>

  • y = 3x

This is the line on the graph B

<u>Note.</u> <em>Its not clear what is needed regarding the table on the bottom</em>
