There are 14 people in an office with 3 different phone lines. If all the lines begin to ring at once, how many groups of 33 people can answer these lines

2184

Step-by-step explanation:

The number of permutations of choosing r things out of n things:

Total people = 14

Number of phone lines = 3

For first call, there are 14 people , one of them will take then for next call there are remaining 13 people and so on. i.e. order matters

Number of permutations =

Required number of ways = 2184

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
