A Los Angeles-area radio station plays songs from a specific, fixed set of artists. The station has no DJ; instead, a computer randomly selects which songs to play. The songs themselves are picked randomly, and the same song may be played many times in a row. In the set of songs, 55% are sung by a female singer, 35% are sung by a male singer, and 10% are instrumental with no vocals. What is the probability that a song with a female singer, a song with a male singer, and an instrumental song will be played, in that order?

Respuesta :

probability 1st song is sung by female : 55/100 reduces to 11/20
probability 2nd song is sung by a male : 35/100 reduces to 7/20
probability 3rd song is instrumental : 10/100 reduces to 1/10

probability of all 3 events happening : 11/20 * 7/20 * 1/10 = 77/4000
