The probabitily is if they get selected as a team of 7 aswell if they're playing a game of some sort.
X2 - 25 = 0
Add 25 on each side.
x2 = 25
Divide by 2 on each side.
x = 12.5
75 time because the proabablity of rolling any number each time is 1/10 so 250/10=25 the mutiples of 3 in 1-10 are 3,6,9 so 3*25 =75 tmes
Answer is -6. Whatever number is closer to 0 when negative will always be bigger. Good luck!
