I would first add 5 and 2 together, then multiply that by 3. Finally you would subtract the 1. After solving for what is inside the parentheses you would multiply it by 2 for your final answer.

2•(3(5+2)-1)
2•(3(7)-1)
2•(21-1)
2•(20)
40

Answer:

$\frac{1}{400}$ or 0.0025 0r 0.25%

Step-by-step explanation:

There are three categories that will get a prize

1) First place = 1 person

2) Second place = 5 persons

3) Third place = 20 persons

A total of 26 people will get prizes.

However, we want to determine your chance to win one of the second place prizes

There are 5 prizes in second place

This means out of a total of 2000 people, you could be among the 5

i.e 5 out of 2000

This is $\frac{5}{2000} = \frac{1}{400} = 0.0025$

This means you have a chance of 1 out of 400

= 0.25%
