A bag contains 6 red marbles, 3 white marbles, and 7 blue marbles. You pick a marble without looking. Find the probability of drawing a white marble.
A. 3/7
B. 7/16
C. 3/16
D. 13/16
Please help please and thank you
To find the probability of drawing a white marble, we need to determine the total number of marbles and the number of white marbles.
The total number of marbles in the bag is given by the sum of the number of red, white, and blue marbles: 6 + 3 + 7 = 16.
The number of white marbles is given as 3.
Now, to calculate the probability of drawing a white marble, we divide the number of white marbles by the total number of marbles:
Probability of drawing a white marble = Number of white marbles / Total number of marbles
Therefore, the probability of drawing a white marble is:
(3 / 16)
So, the correct answer is option C: 3/16.
P(white) = (#whites)/(#marbles)
so, how many marbles are white?
how many total marbles are there?
