ANEK [815]

Answer:

Total number of ways to distribute the prize = 2187

$3^{7}= 2187$

Step-by-step explanation:

Given:

Number of prizes = 7

Number of peoples = 3

We need to find the total number of ways to distribute the prize.

Solution:

From the above statement, 7 prizes are to be distributed between 3 people, wherein each person gets at least one prize.

Each prize is to be distributed among three persons. When the first prize is to be awarded, one of the three is chosen to win the prize. When the second prize is to be awarded, there are again three choices.

So, total number of distribution of the prizes is given as:

$3\times 3 \times 3\times 3\times 3\times 3\times 3=3^{7}$

$3^{7}= 2187$

Therefore, total number of ways to distribute the prizes = 2187
