If the person is picked at random, the the probability is 3/7.
No.
2/5
The probability is always a fraction except when it is 0 or 1. If a probability = 1 then it will definitely happen. If the probability is 0 then it will not happen. If you toss a fair coin the probability of heads is 1/2, and the probability of tails is 1/2. These fractions are representations of the probabilities. Not all fractions are representative of probabilities. Fractions can be used to represent a portion of a whole. Like what portion of a class is boys, and what portion is girls: If there are 8 boys and 7 girls, then the 8/15 of the class is boys, and 7/15 of the class is girls.
13 out of 20
12/27 reduces to 4/9 numerator = the number of acceptable outcomes denominator = total number of outcomes (12 boys + 15 girls)
45 boys are in the class
87
yes there is difftrent class for boys and girls
well it Will be even
there are 12 boys in the class
Divide the number of girls by the total number of children (boys + girls).
The girls are 100% of the females and the boys are 100% of the males
There are 18 girls and 6 boys in the class of 24 students
A fourth of the class are boys, which can be expressed as a fraction as 1/4. Since the class is made up of only boys and girls, and a fourth of the class are boys, the remaining part of the class must be girls. To find the fraction of the class that are girls, you can subtract 1/4 from 1. 1 - 1/4 = 3/4 So, 3/4 of the class are girls.
45 noys
It is not opssible to give a sensible answer to this question. 46+58 = 104. So if the class has 46% girls and 58% boys then the class has 4% who are simultaneously girls and boys.
The ratio of girls to boys in Charlotte's class is 3:2. This is found by dividing the number of girls by the number of boys to get 21/14 = 3/2.
