I need all the answers to the exploring probability practice it has 10 questions.
A bag contains 6 red marbles, 3 white marbles, and 7 blue marbles. You pick a marble without looking. Find the probability of a white marble.
A 3/8
B 7/16
C 3/16
D 13/16
A 3/16
To find the probability of picking a white marble, you need to calculate the ratio of the number of favorable outcomes (white marbles) to the total number of possible outcomes (all marbles).
In this case, the bag contains 6 red marbles, 3 white marbles, and 7 blue marbles. So, the total number of marbles is 6 + 3 + 7 = 16.
The number of favorable outcomes (white marbles) is 3.
Therefore, the probability of picking a white marble is 3/16.
So, the correct answer is C) 3/16.
