This is what I got: 18C3 * 7C2 + 18C4 * 7C1 + 18C5 * 7C0 = 47,124
Is this right?
Well, if there are twice as many boys as girls in a group of 120 children, that means there are 80 boys and 40 girls. So, there are 40 girls in the group. Math doesn't lie, honey.
Let the number of girls be ( x ). Since there are three times as many boys as girls, the number of boys is ( 3x ). Together, the total number of children is ( x + 3x = 4x ). Setting this equal to 80 gives us ( 4x = 80 ), so ( x = 20 ). Therefore, there are 20 girls in the group.
The probability of choosing 2 girls at random from group of 25 students of which10 are girls and 15 are boys is:P( 2 girls) = (10/25)∙(9/24) = 3/20 = 0.15 = 15%
let boys = B and girls = GB +G =120;2G = B;3G = 120;G = 40 and B = 80
I figured out the answer: 18+7 = 25, So 25C5 = 53,130 Teams. This assumes there are no sex restrictions on the teams (for example, "teams must include at least one boy and at least one girl"). That would be a lot more complicated, and if that's a factor you'd need to specify exactly what the restrictions are.
Well, if there are twice as many boys as girls in a group of 120 children, that means there are 80 boys and 40 girls. So, there are 40 girls in the group. Math doesn't lie, honey.
51 girls, 29 boys
There are 40 girls.
This means that for every girl there are two boys - so in a group of three, two will be boys and one a girl 45 ÷ 3 = 15 So, there are 15 girls and 30 boys.
Let the number of girls be represented by x. Since there are twice as many boys as girls, the number of boys would be 2x. Therefore, the total number of children is x (girls) + 2x (boys) = 60. This simplifies to 3x = 60. Solving for x, we get x = 20. So, there are 20 girls in the group of 60 children.
90
Let the number of girls be ( x ). Since there are three times as many boys as girls, the number of boys is ( 3x ). Together, the total number of children is ( x + 3x = 4x ). Setting this equal to 80 gives us ( 4x = 80 ), so ( x = 20 ). Therefore, there are 20 girls in the group.
The names of the [boys][children] Niños means boys but it could mean a group of children composed of both boys and girls. Niñas means girls.
The probability of choosing 2 girls at random from group of 25 students of which10 are girls and 15 are boys is:P( 2 girls) = (10/25)∙(9/24) = 3/20 = 0.15 = 15%
In the community depicted in "The Giver," children are named during the annual Ceremony of Twelve. The Chief Elder announces the children's names, which are chosen based on a list of approved names for each age group. The names are assigned by the community elders, rather than chosen by the parents.
group of people chosen to make decisions in court
The correct punctuation is "girls' group," with an apostrophe before the 's' to indicate that the group belongs to the girls.
