Step-by-step explanation:
"Find the probability that a student chosen at random from those who play a sport  does not watch rugby."

65+71-75=
136-75=
61 people play a sport AND watches rugby

Product of two consecutive integer so this mean that x and y but y = x+1 than
x(x+1)=1332
x^2 +x -1332 =0  so bc. you get 36*37=1332 and 37x-36x=x so you can rewriting this quadratic factorized completlie 
x^2 +x -1332 = 0
(x+37)(x-36)=0
x+37=0
x=-37 so the larger integer result that will be 37

Hello,
A good first step to take would be to calculate how much of a barrel John and Mary can drink together in 1 day.
If John can drink 1 barrel in 6 days, then every day he can drink 1/6 of a barrel.
If Mary can drink 1 barrel in 12 days, then every day she can drink 1/12 of a barrel. 
Every day, the total that John and Mary can drink will be (1/6) + (1/12) = (1/4) of a barrel.
If we want to know how many days it will take for them to drink 1 barrel of water together, and they drink 1/4 of a gallon every day, we do 
(1) / (1/4) = 1 * (4/1) = 4 days
It will take 4 days for John and Mary to drink 1 barrel together.
Hope this helps!
