Explanation: "The number of distinct elements in a finite set is called its cardinal number. It is denoted as n(A) and read as ‘the number of elements of the set’."

In other words, the cardinal number is the amount of numbers in a set... in this case we have 5 numbers. We have 2,3,4,5, and 6. That is 5 numbers total.

Note: Any repeated numbers don't count as an element.

Example: [2,2,2,3,4,5] this set has only 4 elements. It has 2,3,4, and 5.

So the cardinal number of this set is 4.

Your welcome. :-)

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✌✌✌

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
