Question

Out of 8 different balls taken three at a time without taking the same three together

Answer 1

Answer:

56

336

Step-by-step explanation:

there are total 8 different balls

Taking all three ball together

we can take out balls in

⁸C₃  ways

= 8!/(5! * 3!)

= 8 * 7 * 6 / (3 * 2)

= 8 * 7

= 56

if Take balls one by one

then number of ways taking the balls

= 8 * 7 * 6

= 336

of course unique combination  will be 56 only
