Hi Kevin, how did you decide that it must be 40/100 not 40/50?

Hi Kevin 😊. I have a question. For question 3. I think that they could mean both things, it could mean over the total males.

Or it could mean over the total people which is 200.

Because if you read the question over and over again, you will see it makes sense both ways.

"Determine the probability that a student plays tennis, given that the student is a male."

So its asking to calculate the probability of a male tennis player.

It doesnt differentiate abit on which one to take? The 200 or 100.

So how must we know which one to take ??

If you get what i mean 👍Hope to hear soon.😊

for the first question, I started by calculating D, then C, then B and lastly A. Am I wrong to do so?
