Final answer:
To find the probability of exactly 2 blue markers being selected, we use combinations to calculate the number of favorable outcomes and the total number of possible outcomes. The probability is 1/61.
Step-by-step explanation:
To find the probability that exactly 2 blue markers are selected, we need to determine the total number of possible outcomes and the number of favorable outcomes.
Total number of markers = 8 blue + 5 yellow = 13 markers
Total number of ways to select 6 markers from 13 = 13C6 = 1716
Number of favorable outcomes:
Choose 2 blue markers from 8 blue markers = 8C2 = 28
Choose 4 markers from 5 yellow markers = 5C4 = 5
Therefore, the probability of exactly 2 blue markers being selected is 28/1716 = 1/61.
