In the 3rd grade there are 60 kids and ten more girls than boys how many boy costumes and girl costumes will they need

They will need 25 boy costumes and 35 girls costumes.

Step-by-step explanation:

There are x boys.

There are x + 10 girls.

Altogether, there are x + x + 10 students.

Altogether, there are 60 students, so

x + x + 10 = 60

2x + 10 = 60

2x + 50

x = 25  (boys)

x + 10 = 35  (girls)

probability for j is 1/4

while

a is 1/6
