Answer: The probability for both is 1/2

Step-by-step explanation:

For A. The probability for who do or do not participate in some kind of sport is found by adding the students who do or do not. Which is 25 + 225 = 250

250 out of 500 simplified is 1/2

For B. The probability got who do and do not participate in some kind of sport is found by taking the number of students out of the whole number. Its 250 out of 500.

250 out of 500 is simplified to 1/2.

So your answer isn't correct. I think it would be a negative number or decimal because 6 is larger than 3. Hope this helps!

it is u(u+6)=3

I got u=6
