Question

a bag contains 10 red marbles, 10 white marbles, and 10 blue marbles. what is the minimum no. of marbles you have to choose randomly from the bag to ensure that we get 4 marbles of same color?

Answer 1

Answer:

10 and mark me as brainilest

Step-by-step explanation:

• Apply pigeonhole principle.
• No. of colors (pigeonholes) n = 3
• No. of marbles (pigeons) K+1 = 4
• Therefore the minimum no. of marbles required = Kn+1
• By simplifying we get Kn+1 = 10.
• Verification: ceil[Average] is [Kn+1/n] = 4
• [Kn+1/3] = 4
• Kn+1 = 10
• i.e., 3 red + 3 white + 3 blue + 1(red or white or blue) = 10
