Step-by-step explanation:
Answer: 
or 30%
Step-by-step explanation:
We will divide the wanted outcomes by the possible outcomes.
The prime numbers from one through fifty are; 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, and 47.
-> This is 15 numbers
That's like asking "What's the dollar amount of one half ?"
"Half" is not an amount. It's half of some amount that's been
previously described.
8.15% isn't an amount of anything.
It's 0.0815 of some amount that's already been described.
You have 12 girls out of 32, so that's 20 boys. Take your amount of boys divided by your total number. So, 20/32 = .625
You want a percentage, so .625 x 100 = 62.5% boys
