Difficulty: Easy
Correct Answer: 4/7
Explanation:
Introduction / Context:
Single-draw colour probability with equally likely balls is computed by favourable/total.
Given Data / Assumptions:
Concept / Approach:
P(white) = 8/14, then reduce the fraction.
Step-by-Step Solution:
P = 8/14 = 4/7 after dividing by 2.
Verification / Alternative check:
P(black) = 6/14 = 3/7; 4/7 + 3/7 = 1 confirms complementarity.
Why Other Options Are Wrong:
3/4 and 4/5 overstate the probability; 1/8 confuses with the inverse count.
Common Pitfalls:
Not simplifying the fraction; mixing counts for colours.
Final Answer:
4/7
