We know that choosing and arrangement of r items out of a total of n items is done by the method of permutation.
The formula is given by:
Here we have to chose 3 entries and arrange them according to there ranks.
Hence, we have n=20 and r=3
Hence, the formula is given by:
Answer:
B) 14
Step-by-step explanation:
We can plug in the values of m and p into the equation:
1/2 m + 3p = 1/2 (16) + 3 (2) = 8 + 6 = 14.
The answer is D
Steps
Take the root of both sides and solve
