In a box, there are 8 red, 7 blue and 6 green balls. One ball is picked up randomly. What is the probability that it is neither red nor green?
- A.
3/4
- B.
7/19
- C.
1/3
(Correct Answer) - D.
8/21
Explanation
1. Total Number of Balls:
Total Balls=8(Red)+7(Blue)+6(Green)
2. Identifying Favorable Outcomes:
The condition is "neither red nor green". This means the ball must be Blue.
Favorable Outcomes (Blue)=7
3. Probability Calculation:
P(E)=Total Number of OutcomesNumber of Favorable Outcomes
4. Simplification:
Correct Answer: Option C
