A class has 12 boys and 16 girls. The teacher writes each student’s name on a different note card and then places the cards in a bag. If the teacher randomly selects one card from the bag, what is the probability that a boy’s name will be selected?

Sagot :

12+16=28 Probability of a boy: =12/28 =6/14 =3/7 =42.86% Hope this helps =)
add the number of boys and girls

12 + 16 = 28

Then divide the number of boys and the total number of student (boys + girls)

Since probability is equal to the number of chance over to the total number of possibility.

12/28

Therefore

3/7 probability for a boy's name to be pick.

or simply

43%

or

0.4285714285714286 probability

I hope it helps
