Answer:
17C5+11C5
Step-by-step explanation:
Well there are 17 and chooses 5 that's 17C5
there are 11 men abd chooses 5 that's 11C5
so add them up
17C5+11C5
The combination helps us to know the number of ways an object can be selected without a particular manner. The number of ways in which 5 men and 5 women can be selected is 2,858,856.
Permutation helps us to know the number of ways an object can be arranged in a particular manner. A permutation is denoted by 'P'.
The combination helps us to know the number of ways an object can be selected without a particular manner. A combination is denoted by 'C'.
[tex]^nC_r = \dfrac{n!}{(n-r)!r!}\ , \ \ ^nP_r = \dfrac{n!}{(n-r)!}[/tex]
where,
n is the number of choices available,
r is the choices to be made.
Given that from a group of 17 women and 11 men, a researcher wants to randomly select 5 women and 5 men for a study.
Now, the number of ways for selection can be written as,
Number of ways in which men can be selected = ¹¹C₅ = 462
Number of ways in which women can be selected = ¹⁷C₅ = 6188
Further, the number of ways for selection can be written as,
Number of ways = Number of ways in which men can be selected × Number of ways in which women can be selected
Number of ways = 462 × 6188
Number of ways = 2,858,856
Hence, the number of ways in which 5 men and 5 women can be selected is 2,858,856.
