The probability that the first two songs played are slow songs 2/20.

What is probability?

Probability is a the chance of happening an event or incident.

The probability can be calculated in terms of the ratio of the the number of probable outcomes to the total number of events in the sample space.

Given, among 5 songs in a CD, 2 are slow songs and 3 are fast songs. It is also mentioned that the songs are not repeated.

Here, the probability of the first song played is slow song = 2/5.

The probability of the second song played is slow song = 1/4.

Therefore, the probability that the first two songs played are slow songs

= (2/5) × (1/4) = 2/20 = 1/10.

Hence, option B is correct.
