Given:
Number of red marbles = 5
Number of blue marbles = 4
Number of yellow marbles = 3
To find:
The probability of pulling a red marble, then pulling a blue marble, without replacement.
Solution:
Probability formula:
We have,
Number of red marbles = 5
Total number of marbles is:
Probability of getting a red marble is:
After selecting one red marble, the remaining number of marbles is 11 and the number of blue marbles is 3. So,
Now, the probability of pulling a red marble, then pulling a blue marble, without replacement is:
Therefore, the correct option is B.
