Question

A local high school is raffle off a college scholarship to the students in its junior class, If a girl has a 0.55 chance of winning the scholarship and 154 of the juniors are girls, how many of the juniors are boys? (Assume that every junior has an equal chance to win.)

Answer 1

Answer: 126

Step-by-step explanation:

55% of student population is girls

if there are 154 girls then
0.55x = 154, where x represents school population

x=280

assuming the school only has boys and girls, anyone that's not a girl must be a boy, so

boys = 280 - 154 = 126.

if the school is not only boys and girls,

there will be 126 or less boys
