You must select a team from a group of 6 boys and 10 girls. How many ways can you select 2 boys and 5 girls?

Keith_Richards [23]

Using the combination formula, it is found that you can select 2 boys and 5 girls in 2,520 ways.

In this problem, Joao and Elisa would be the same team as Elisa and Joao, hence the order is not important and the <em>combination formula</em> is used to solve this question.

<h3>What is the combination formula?</h3>

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem:

2 boys are selected from a set of 6.

5 girls are selected from a set of 10.

Hence:

$T = C_{5,2}C_{10,5} = \frac{5!}{3!2!} \times \frac{10!}{5!5!} = 2520$

You can select 2 boys and 5 girls in 2,520 ways.

1/3log125/8-2log2/5+log80/125

morpeh [17]

Answer:

$3log2$

Step-by-step explanation:

Given

$\frac{1}{3} log( \frac{125}{8} ) - 2 log( \frac{2}{5} ) + log( \frac{80}{125} )$

Required

Solve

Apply logarithm rules

$log( \frac{125^{\frac{1}{3}}}{8^{\frac{1}{3}}} )- log( \frac{2^2}{5^2} ) + log( \frac{80}{125} )$

$log( \frac{5}{2}} )- log( \frac{4}{25} ) + log( \frac{80}{125} )$

Apply quotient rule

$log( \frac{5}{2} / \frac{4}{25} ) + log( \frac{80}{125} )$

$log( \frac{5}{2} * \frac{25}{4} ) + log( \frac{80}{125} )$

$log( \frac{100}{8} ) + log( \frac{80}{125} )$

Apply product rule

$log( \frac{100*80}{8*125} )$

$log( \frac{8000}{1000} )$

$log(8)$

Express 8 as 2^3

$log(2^3)$

$3log2$
