Answer 1

sorry dude i donot know the answer

Answer 2

Answer:

The total number of ways in which the horses can graze the grass of the field = 210

Step-by-step explanation:

The horses who entered the field : h1 , h2 , h3

Number of horses who entered the field = 3

The given portions into which the horses are made to enter : p1 , p2 , p3 , p4 , p5 , p6 , p7

Total number of portions = 7

So, we need to find the number of ways in which the horses are made to enter the 7 portions given that no two horses can enter the same portion

Now, h1 horse can graze the grass in 7 ways

Also, h2 can graze the grass in 6 ways

And, h3 can graze the grass in 5 ways.

So, Total number of ways = 7 × 6 × 5

Hence, The total number of ways in which the horses can graze the grass of the field = 210
