You look over the songs in a jukebox and determine that you like 14 of the 53 songs. (a) what is the probability that you like the next four songs that are played? (assume a song cannot be repeated.) (b) what is the probability that you do not like the any of the next four songs that are played? (assume a song cannot be repeated.)

a) Pr(liking four)=0.00342

b) Pr( not liking four)= 0.281

Step-by-step explanation:

The probability is mutually dependent in that the songs cannot be repeatd

total number of songs =53

number of songs likes =14

the probability of liking the first song is 14/53

since the songs cannot be repeated, the probability of  liking the next song is 13/ 52 ( because there are now only 13 songs liked on the jukebox out of 52). this continues in like manner for the third and fourth as 12/51 and 11/50 respectively .

a) the probability of liking all four will be

Pr(liking four) =Pr (liking first)* Pr(liking second)*Pr(liking third)*Pr(liking fourth)

= to 3 significant figures

Pr(liking four)=0.00342

b) total number of songs =53

number of songs likes =14

no of songs not liked is

following the same pattern as in (a) since the events are dependent,

we have

Pr(not liking four) = Pr (not liking first)* Pr( not liking second)*Pr(not liking third)*Pr( not liking fourth)

Pr( not liking four)= 0.281 to 3 significant figures
