Gap Method - Separation: Worksheet 6 - Intermediate-Advanced Practice Gap Method - Separation INTERMEDIATE ADVANCED

Step-by-Step Solution:

Concept: Gap Method - used when certain items must be separated.

Strategy:
1. Arrange the items that don't have restrictions
2. Identify gaps where restricted items can be placed
3. Place restricted items in available gaps

Given:
- Consonants: 5
- Vowels: 2
- Constraint: No two vowels together

Step 1 - Arrange Consonants:
Arrange 5 consonants: 5! = 120 ways

Step 2 - Identify Gaps:
When 5 consonants are arranged: _ C _ C _ C _ ... _ C _
Number of gaps (including ends) = 6

Visual: If we have 5 consonants, we get 6 positions where vowels can go.

Step 3 - Place Vowels in Gaps:
Choose 2 gaps from 6 available gaps: C(6,2) = 15
Arrange 2 vowels in chosen gaps: 2! = 2

Step 4 - Apply Multiplication Principle:
Total arrangements = 120 × 15 × 2
= 120 × 15 × 2
= 3600

Key Technique: Gap method ensures no two restricted items are adjacent by placing them in gaps created by unrestricted items.

Verification: Check that 2 ≤ 6 (we need enough gaps).

Step-by-Step Solution:
