Suppose a bus arrives at a bus stop every 40 minutes. if you arrive at the bus stop at a random time, what is the probability that you will have to wait at least 10 minutes for the bus? write the probability as a simplified fraction.
pl hahaha

=3/4

Step-by-step explanation:

A bus arrives at a bus stop every 40 minutes.

You arrive at a bus stop at a random time.

So, probability that you will wait at most 10 minutes = 10/40

So, The probability that you will wait at least 10 minutes= 1-10/40

=1- 10/40

By taking L.C.M we get;

=40-10/40

=30/40

=3/4

Thus the probability that you will have to wait at least 20 minutes for the bus is 3/4

yes
