In how many ways can 10 people be divided into three groups with 2, 3, and 5 people respectively?

Liula [17]

Answer:

2100

Step-by-step explanation:

In how many ways can a group of 10 people be divided into three groups consisting of 2,3, and 5 people?

First, you need to choose 4 people to fill the first group.

The number of ways is (104) which equals to 210.

Then, pick 3 more people out of the remaining 6 to be in the second group. And then, pick 3 more out of the remaining 3.

However, we need to divide it by 2, since we don’t really care on the order of selection of group.

(63)(33)/2=10

So, there are 210 x 10 = 2100 ways

Answer:

$-\frac{3}{4}$ meters

Step-by-step explanation:

From the answer choices, we basically need to find which of them is between $-\frac{1}{2}$ and $-1\frac{2}{3}$

Converting all of them to decimals would make it really easier:

So we need to find number between -0.5 and -1.67

Answer choice A is -2.33

Answer choice B is -0.75

Answer choice C is -0.25

Answer chioce D is -1.83

So which number, from the choices, is between -0.5 & -1.67?

Clearly, it is -0.75, or, $-\frac{3}{4}$ meters
