Answer: C. 11/102
Step-by-step explanation:
Given Data:
Red ball = 11
Blue ball = 7
Total no of balls = 18
What is the probability that choosing 4 balls all are red.
1. Probability of picking a red ball
= 11/18
2. Probability of picking a blue ball
= 7/18
3. Probability of picking 4 red balls in a roll.
= 11/ 18 * 10/17 * 916 * 8/15
= 11/102
Or
10.8% chance of all 4 balls being red.
