To find the probability of drawing 2 pink marbles, we need to know the total number of marbles in the bag as well as the number of pink marbles.
The total number of marbles in the bag is the sum of the number of pink, yellow, and blue marbles:
Total marbles = 3 pink + 2 yellow + 5 blue = 10 marbles
Next, we need to find the probability of drawing 2 pink marbles from the bag. To do this, we will use the concept of combinations.
The number of ways to choose 2 pink marbles from the 3 available pink marbles can be calculated using the combination formula:
C(n, r) = n! / (r! * (n - r)!)
In this case, n = 3 (number of pink marbles) and r = 2 (number of pink marbles we want to draw).
C(3, 2) = 3! / (2! * (3 - 2)!) = 3
So, there are 3 ways to choose 2 pink marbles from the 3 pink marbles in the bag.
The total number of ways to choose 2 marbles from the 10 marbles in the bag can also be calculated using the combination formula:
C(10, 2) = 10! / (2! * (10 - 2)!) = 45
Therefore, there are a total of 45 ways to choose any 2 marbles from the bag.
Finally, we can find the probability of drawing 2 pink marbles by dividing the number of favorable outcomes (ways to choose 2 pink marbles) by the total number of outcomes (ways to choose any 2 marbles):
Probability = ways to choose 2 pink marbles / ways to choose any 2 marbles
Probability = 3 / 45 = 1/15
So, the probability of drawing 2 pink marbles is 1/15 or approximately 0.067.
