Answer:  0.2

Step-by-step explanation:

Number of ways to select r things out of n things = ^nC_r=\dfrac{n!}{r!(n-r)!}

Then , Total number of ways to select 2 out of 5 chores = ^5C_2=\dfrac{5!}{2!3!}=\dfrac{5\times4\times3!}{2\times3!}=10

Number of ways to selecting first 2 on list = 2 (either he choose top on the list first then second , or second person first then topper)

Now , the probability he will choose the first 2 on list = \dfrac{2}{^5C_2}=\dfrac{2}{10}=0.2

Hence, the probability he will choose the first 2 on list is 0.2.

25x=2544 what does x represent
Georgia [21]
Hey there! 

Firstly, we are going to divide by 25 on each of your sides because it paired off with a variable

Here's what I meant! 

\frac{25x}{25} =  \frac{2,544}{25}

We would have to cancel out the: \frac{25x}{25} because it gives us 1

Answer: x =  \frac{2,544}{25}

Good luck on your assignment and enjoy your day!
