Question

Eric puts several CDS in a case . four CDS are country, six are rap and ten are pop. if Eric picks one CD from the case without looking, what is the probability that he will pick a pop CD.

A 3/10
B 1/4
C 1/3
D 1/2

Answer 1

Explanation:

Eric has a total of 4 + 6 + 10 = 20 CDs in the case.

The probability of picking a pop CD is the number of pop CDs divided by the total number of CDs:

P(pick a pop CD) = 10/20 = 1/2 = 0.5

Therefore, the probability of Eric picking a pop CD is 0.5 or 50%.

Answer 2

There are a total of 4 + 6 + 10 = 20 CDs in the case. Eric has a 10/20 = 1/2 chance of picking a pop CD since there are 10 pop CDs in the case.

Therefore, the answer is D) 1/2.
