no ane boys are not in the club
25 balls, 13 are odd
first pick = 13/25 probability of picking an odd
2nd pick = 12/24 = 1/2 probability
13/25 x 1/2 = 13/50 probability
You want to solve for x so add 18 from both sides of the equal sign. making it 3x=12. then divide both sides by 3 making x=4. x is 4.
5.28....What you do is find the hundredth place then locate the number to the right of it. If the number is greater than 4, then you round the hundredth place up a number and if it is less than or equal to 4 then leave the hundredth place alone. but in this case we round it up because 5 is greater than 4 so change 7 to eight.
