A bag contains 10 yellow, 15 blue and
5 red Marbles. Mark chooses a candy and doesn't replace it in the bag.
Find P (neither blue)
What nonsense!
I just found your blog and love this idea! What size did you make your book tags, so that there was enough room for the kids to write on them? Thanks!! :)
To find the probability of Mark choosing a candy that is neither blue, we first need to determine the total number of marbles in the bag.
The bag contains 10 yellow marbles, 15 blue marbles, and 5 red marbles.
The total number of marbles in the bag is:
10 (yellow) + 15 (blue) + 5 (red) = 30 marbles
Now, to find the probability of Mark choosing a marble that is neither blue, we need to find the number of marbles that are not blue.
The number of marbles that are not blue is:
10 (yellow) + 5 (red) = 15 marbles
Therefore, the probability of Mark choosing a candy that is neither blue is:
P(neither blue) = Number of marbles that are not blue / Total number of marbles
P(neither blue) = 15 marbles / 30 marbles
Simplifying the fraction, we get:
P(neither blue) = 1/2
So, the probability of Mark choosing a candy that is neither blue is 1/2.
