a bag contains 6 red marbles, 5 yellow marbles, 7 blue marbles, and 4 white marbles. if one marble is drawn at random from the bag, what is the probability that it will be white?
the answer i got is 2 over 11 . is this correct?
Yes, it is correct.
To find the probability of drawing a white marble, you need to determine the favorable outcomes (drawing a white marble) over the total possible outcomes (drawing any marble from the bag).
In this case, the favorable outcome is drawing a white marble, and there are 4 white marbles in the bag.
The total possible outcomes are the number of marbles in the bag in total, which is 6 red marbles + 5 yellow marbles + 7 blue marbles + 4 white marbles = 22 marbles.
So, the probability of drawing a white marble is 4/22, which simplifies to 2/11.
Therefore, your answer of 2/11 is correct.
