Just took the final got it correct
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
Im pretty sure it would be 0.2
