The probability that a pin code has at least one repeating digit is 0.6976.
To begin with, in all scenarios, the initial digit should not be zero = 9x10x10x10x10
Cases of non-repitition are currently = 9×9×8×7×6
Thus, at least one repeat = Total - no repetition
Probability = 1-((9X9X8X7X6)/(9×10×10×10×10))
= 0.6976
What is probability?
Mathematical descriptions of the likelihood that an event will happen or that a proposition is true are dealt with in the discipline of mathematics known as probability. The probability of an event is a number between 0 and 1, where 1 denotes a certainty and 0 denotes an impossibility of the event.
Why do we use probability?
The concept of probability tells us how likely a certain event is to occur. For instance, weather patterns are used by meteorologists to forecast the likelihood of rain. The link between exposures and the risk of health impacts is understood in epidemiology using probability theory.
