Answer:
Brandon is correct.
Step-by-step explanation:
Initially, there id 4 pints of green paint in the bucket.
As the green paint is made from equal amounts of yellow paint and blue paint, so, the initial amount of yellow and blue paint in the bucket is 2 pint each.
Let x pints of yellow paint to be added to the bucket to make the desired shade.
Total amount of the paint in the bucket, after addition of pints of yellow color become
pint, in which the ampunt of yellow color is
pints.
As, the ampunt of yellow color is 80% of the total amount of the mixture, so
So, 6 pints of yellow paint to be added to the bucket to make the desired shade.
Hence, Brandon is correct.
The probability of getting red marble from the consider withdrawal of a marble is 0.107 approximately.
<h3>How to calculate the probability of an event?</h3>Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
Given that:
The bag contains:
- 5 green marbles,
- 6 red marbles,
- 45 white marbles.
- Rafael draws one marble at random
Since he draws one marbel, thus, only one colored marble would come out.
Let we suppose we've to find P(red marble coming out).
Then, if we take:
E = event of Rafael drawing a red marble,
then E can be done in 6 ways as there are 6 red marbles to choose from.
Also, withdrawal of 1 marble (of any color) can be done in (5+6+45 = 56) 56 ways.
Thus, we get:
Thus, the probability of getting red marble from the consider withdrawal of a marble is 0.107 approximately.
