A bag contains 2 red marbles, 7 blue marbles and 5 green marbles. If two marbles are drawn out of the bag, what is the exact pro bability that both marbles drawn will be blue?
1 answer:
Answer:
0.25 or 25%.
Step-by-step explanation:
2 Red + 3 Blue + 7 Green = 12 Total Marbles.
You have 3 blue marbles out of the total marbles, so 3/12, then simplify it. 3/12 = 1/4. This gives you 0.25, or 25%.
The probability of drawing a blue marble is 0.25 or 25%
