Answer:
7/136
Step-by-step explanation:
To find the probability in this case, you have to do 12 ( the number of blue marbles ) / 34 ( the total number of marbles ) X 14 ( the number of clear marbles ) / 33 (total number of marbles after one is taken away) X 11 ( the number of blue marbles after a blue marble is taken away ) / 32 ( the number of marbles left after two is taken away ). The answer is 42/816, which reduces into 7/136.
Answer:
The probability is 0.0514.
Step-by-step explanation:
Maria has 8 black marbles, 14 clear marbles, and 12 blue marbles in a bag.
Total marbles are = [tex]8+14+12=34[/tex]
The requires probability is :
[tex]\frac{12}{34} \times\frac{14}{33} \times\frac{11}{32}[/tex]
= [tex]\frac{1848}{35904}[/tex]
= 0.0514
