Probability of Drawing 5 Pencils of the Same Color

In a box, there are 20 pencils, including 6 blue, 6 red, 6 green, and some black with brown. We want to determine the probability of drawing 5 pencils of the same color.

The probability of drawing 5 pencils of the same color can be calculated using the concept of combinations. The formula for calculating the probability of an event is:

Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

Let's calculate the probability for each color.

- Blue Pencils: - Total blue pencils = 6 - Total pencils = 20 - Probability of drawing 5 blue pencils = (6 choose 5) / (20 choose 5).

- Red Pencils: - Total red pencils = 6 - Total pencils = 20 - Probability of drawing 5 red pencils = (6 choose 5) / (20 choose 5).

- Green Pencils: - Total green pencils = 6 - Total pencils = 20 - Probability of drawing 5 green pencils = (6 choose 5) / (20 choose 5).

- Black with Brown Pencils: - Total black with brown pencils = (20 - 6 - 6 - 6) = 2 - Total pencils = 20 - Probability of drawing 5 black with brown pencils = (2 choose 5) / (20 choose 5) (This probability will be 0 as the number of favorable outcomes is less than 5).

After calculating the probabilities for each color, we can compare and determine the probability of drawing 5 pencils of the same color.
