4) None of these

Read Solution (Total 1)

total balls = 18

imagine that there r 3 boxes

without replaceent

we can add any 1 of the 18 in first box and for the second box the total will be 17 as we have put one ball in the first one and then the second one we can add 16

so 18 x 17 x 16

4896 ways

with replacement

we can add any one of 18 balls into any boxes as they r replaced

so 18 x 18 x 18

5832 ways
