Answer:
[tex] P= \frac{x}{n}[/tex]
Where x represent the successes and n the total of marbles and replacing we got:
[tex]P= \frac{3}{8}= 0.375[/tex]
Step-by-step explanation:
For this case we have the following types of marbles
3 white, 3 yellow, 2 black
The total of marble for this case are:
[tex] n = 3+3+2= 8[/tex]
And we have a total of 3 yelow marbles. We can apply the definition of probability given by:
[tex] P= \frac{x}{n}[/tex]
Where x represent the successes and n the total of marbles and replacing we got:
[tex]P= \frac{3}{8}= 0.375[/tex]
Answer:
[tex]\frac{3}{8}[/tex]
Step-by-step explanation:
In order for us to calculate the probability, we will use the following principle. The probability of an event A is given by the number of chances we get to have that event, divided by the total of chances.
IN this case, let A be the event that we get a yellow marble. Note that in total, we have 8 marbles (3 yellow, 3 white and 2 black). So, if we are going to pick a marble at random, we have 8 possibilities for picking any marble. Since we are interested in the yellow ones, we have 3 possibilities of getting a yellow marble. Hence the probability of getting a yellow marble is 3/8.
