True or false
1.the number of permutations of r objects out of n (r > 1), is greater than the number of combinations of r objects out of n.

True

Step-by-step explanation:

Permutation is act of arranging members of a set while combination is selection of the items from collection.

The number of permutation of r object out of n is:

The number of combinations of r object out of n is:

Or,  

So, number of the permutations of r objects out of n is greater than number of the combinations of r objects out of n.

Since we know the ratio is 5:2, brian got the lesser and his amount was 156, if we divide 156 by 2, we get 1/5th the value of Bogie's amount. 156/2 is 78, so multiply 78 by 5 and we get 390. Our ratio becomes 390:156, and 390 is your answer
