The number of brownies Lauren brought to the class is 35.
A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
The number of brownies given to her three friends = 3/5
3/5 = 21 brownies
Now,
The total brownies she brought to the class.
3/5 = 21 brownies
Multiply 5/3 on both sides.
1 = 5/3 x 21 brownies
1 = 35 brownies
Thus,
She brought 35 brownies to the class.

What is the probability that the golf ball he selects is white or pink?
A.5/54
B.13/5
C.5/13
D.13/18
Answer: The correct option is (D)
Step-by-step explanation: Given that a bucket hold holds 10 white golf balls, 3 pink golf balls, and 5 yellow golf balls. Jason selects 1 golf ball from the bucket at random.
We are to find the probability that the golf ball he selects is white or pink.
Let, 'A' denotes the event that the golf ball that Jason selects is either white or pink.
Then, n(A) = 10 + 3 = 13.
Let, 'S' denotes the sample space for the experiment.
Then, n(S) = 10 + 3 + 5 = 18.
Therefore, the probability that the probability that the golf ball Jason selects is white or pink is given by
Thus, the required probability is
Option (D) is correct.
