A bag contains 3 red marbles, 5 blue marbles, and 4 black marbles. Jenna draws a black marble and does not replace it. What is the probability of drawing a black marble next?
ok it 3/11 i believe
yes
11 left in bag and 3 are black
To find the probability of drawing a black marble next, we need to consider the total number of marbles remaining in the bag and the number of black marbles remaining.
After Jenna draws a black marble and does not replace it, there are a total of 11 marbles remaining in the bag (since one black marble has been removed). Out of these 11 remaining marbles, there are still 3 black marbles left.
Thus, the probability of drawing a black marble next can be calculated as the number of favorable outcomes (drawing a black marble) divided by the number of possible outcomes (total number of marbles remaining):
Probability = Number of black marbles / Total number of marbles remaining
Probability = 3 / 11
Therefore, the probability of drawing a black marble next is 3/11.
To find the probability of drawing a black marble next, we need to know the total number of marbles remaining in the bag after Jenna draws a black marble.
Initially, there are a total of 3 + 5 + 4 = 12 marbles in the bag.
Since Jenna draws a black marble and does not replace it, there will now be a total of 12 - 1 = 11 marbles remaining in the bag.
Out of the 11 remaining marbles, there are still 4 black marbles.
Therefore, the probability of drawing a black marble next is: 4/11.
So, the probability of drawing a black marble next is 4/11 or approximately 0.364.
