answer: there are 175 ways to put all the lamps on the tables .

step-by-step explanation:

since we have given that

number of identical lamps = 10

number of identical tables = 3

we need to find the "number of ways to put all the lamps on the tables" for this we will use "combination ":

number of ways to put all the lamps on the tables is given by

$^{10}c_{1}+^{10}c_2+^{10}c_3\\\\10+\frac{10\times 9}{2\times 1}+\frac{10\times 9\times 8}{3\times 2\times 1}\\\\=10+5\times9+120\\\\=10+45+120\\\\=175$

so, there are 175 ways to put all the lamps on the tables .
