Answer 2

10!/2! =  1814400  ways 8 socks can  be pulled out of the box,

Step-by-step explanation:

Box contains 3 red, 3 blue and 4 white socks

Total Socks = 3 + 3 + 4 = 10

Assuming Socks are distinct

number of  ways 8 socks can  be pulled out of the box, if order is important

= ¹⁰P₈

= 10!/2!

= 1814400

if Order is not important

then number of ways = ¹⁰C₈  = 10!/(8! * 2!)  =  10 * 9 /2  = 45 Ways
