The amount of the final solution is 4 + 1 = 5 quarts.
The amount of alcohol in the final solution is 5 * 0.36 = 1.8 quarts.
The concentration of alcohol in the 4 quarts of alcohol solution that was added is:
When multiplying fractions, multiply the numerators (top part of fraction) with numerators and denominators (bottom part of fraction) with denominators.

then can be calculated via:
1507 are the different ways can 5 baseball players and 4 basketball players be selected from 12 baseball players and 13 basketball players
<em><u>Solution:</u></em>
Given that,
5 baseball players and 4 basketball players be selected from 12 baseball players and 13 basketball players
This is a combination problem
Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter
<em><u>The formula is given as:</u></em>
Where n represents the total number of items, and r represents the number of items being chosen at a time
<em><u>Let us first calculate 5 baseball players from 12 baseball players</u></em>
Here, n = 12 and r = 5
<em><u>For a number n, the factorial of n can be written as:</u></em>
Therefore,
<em><u>Similarly, 4 basketball players be selected 13 basketball players</u></em>
n = 13 and r = 4
Similarly we get,
<em><u>Thus total number of ways are:</u></em>
Thus there are 1507 different ways
