Given the two sets: A=(1, 2, 3)
B =(3, 2, 1)
Which of the following is a true statement?
O 4EB
O ACB
O A is an infinite set
none of the above

none of the above bcoz set a is set of first 3 natural no.in ascending order. and set b is set of first 3 natural no. in descending order

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
