(a) How many children over 11 and under 18 had played Little League?

(a) How many children over 11 and under 18 had played Little League?

Answer 1

Let's start by organizing what we know from the information you shared:

247 children below 18.

110 males & translates to 137 females.

 

Of the 247 children, 137 are under 11.

73 males are under 11 & translates to 64 females

Of the 247 children, 145 have played little league.

46 females under 11 played LL.

33 males under 11 played LL

 

(a) The 'teen/tween' bracket is the 145 LL players minus the boys and girls under 11, or:

t = 145 - 46 - 33

t = 145 - 79

t = 66

 

So 66 children between the ages of 11 and 18 have played little league.
