Concept:
The concept of probability means the likelines of the event to take place or not. probability can be used to identify a certain event or an impossible event. probability is always between zero and one.
Given:
we are given that a bus comes between 6 a.m. and 9:00 p.m. by every 30 minutes.
Find
We need to find the probability that a person will have to wait for at least 10 minutes if he reach is at random during this time period.
Solution:
to find the probability of this event we will first see the number of likely events in the favour of the event and the total number of events.
30 minutes time duration will have 30 total events.
And the chances of the likely even is only 1.
the probability will be=1/30.
Therefore, we get that the probability that he will have to wait for at least 10 minutes is 1/30.
