Answer:
The correct option is B. 252
Step-by-step explanation:
Total number of peoples in the group = 10
Number of peoples needed to be selected from the group of 10 peoples = 5
We need to find the total number of ways in which we can select the 5 peoples.
[tex]\text{So, Number of ways of selecting the 5 people out of 10 = }_5^7 \txterm{C}[/tex]
[tex]\text{So, Number of ways of selecting the 5 people out of 10 = }\frac{10!}{5!\times 5!}[/tex]
[tex]\text{So, Number of ways of selecting the 5 people out of 10 = }252[/tex]
Hence, Total number of required ways = 252
Therefore, The correct option is B. 252
