Assuming that there are only 400 musicians belonging to the high "Danceability" category (Danceability describes how suitable a track is for dancing based on a combination of musical elements including tempo, rhythm stability, beat strength, and overall regularity. A value of 0.0 is least danceable and 1.0 is most danceable.) and 132 of them are pop music artists and the rest are Rock music artists.

Which of the following statements is/are true?

a.If I randomly extracted 20 songs that belong to this Danceability category,the probability that more than 10 of them will belong to Pop music artists is 0.968.

b.Now imagine I am randomly picking balls without replacement, from an urn containing red(132) balls and blue(268) balls, the probability of choosing exactly 15 red balls out of the 40 balls I picked, will be 0.112.

c.If I randomly extracted 20 songs that belong to this Danceability category,the probability that more than 10 of them will belong to Rock music artists is 0.918.

d.Now imagine I am randomly picking balls with replacement, from an urn containing red(132) balls and blue(268) balls, the probability of choosing exactly 15 red balls out of the 40 balls I picked, will be 0.891.
