Answer:
4/23
Step-by-step explanation:
Probability of choosing a red marble = # of red marbles / total # of marbles
We are told that there are 4 red marbles and 19 blue marbles
So the # of red marbles = 4
And the total # of marbles = 4 + 19
4 + 19 = 23
So there are a total of 23 marbles
Recall that probability of choosing a red marble is equal to # of red marbles / total # of marbles
Hence, the probability of choosing a red marble is 4/23
Note: 4/23 is already in it's simplest form so no simplifying has to be done.
Answer:
14/33
Step-by-step explanation:
There are 14 red marbles and 19 blue marbles, meaning that there are 33 marbles in all:
14 + 19 = 33
You are randomly choosing a red marble out of the total amount of marbles. 14/33
Note that you cannot simplify the fraction anymore, and so 14/33 is your answer.
