Step 1
a) Uniform distribution: If the probability of ocurance of every event is same then we use Uniform distribution.
Example: Probability of getting head or tails is Uniform distribution.
Step 2
b) Exponential distribution: It is used to find the waiting time for an event to occur.
Example: To find the time taken for the failure of any hardware(failure of bulb).
The amount of time one needs to wait until the next bus arrives at a busstop.
Step 3
c) Bimodal distribution: It is a collection of data with 2 peaks(modes).
Example: Arrival of customers at restaurant. If you plot the arrival rate of customers at restaurant you may notice 2 peaks,1 Peak during lunch and other during Dinner.
