Class 11 Mathematics Permutations and Combinations Derivations of formulas and their connections Easy Level 66

यदि (5) अलग points में से directed arrow बनाने हों तो कौन-सा formula connection सही है?

If directed arrows are to be made from (5) distinct points which formula connection is correct?

Explanation opens after your attempt
Correct Answer

B. \(^{5}P_2\)

Step 1

Concept

In a directed arrow changing start and end changes the arrow. In exams use ordered pair or permutation when direction exists.

Step 2

Why this answer is correct

The correct answer is B. \(^{5}P_2\). In a directed arrow changing start and end changes the arrow. In exams use ordered pair or permutation when direction exists.

Step 3

Exam Tip

Directed arrow में start और end बदलने से arrow बदल जाता है। परीक्षा में direction हो तो ordered pair यानी permutation लगाएँ।
