In classroom A there are 35 children and 60% are girls. In classroom B there are 36 children and the ratio of girls to boys is 5: 4.
Which classroom has more girls?

classroom A

Step-by-step explanation:

because there are 35 children and 60% out of 100% are girls. therefore 40% of the 35 children are boys

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

answer: group b.
