music: 37 min.

If Lenny chooses a time of day at random to turn on the radio to his favorite station, what is the probability that the news will be on?

A). 37/60
B). 1/15
C). 19/60
D). 19/37

Respuesta :

Answer: choice C) 19/60

----------------------------------------------------------------------------------------------------

Explanation: 

Add up the minute values: 19+4+37 = 60

We have a total of 60 minutes. Of that total, 19 minutes is dedicated to news.

Divide the two values (19 and 60) to get the fraction 19/60. We can't reduce from here so we leave it like that.
