Explanation of Solution
Given information:
The given statement is:
“A die is rolled twice. What is the probability of rolling two different numbers?”
Formula used:
The following formula is used:
Calculation :
The result of one rolling does not affect the result of another, so it is an independent event.
The probability of getting two different numbers can be calculated by:
Hence, the event is independent and the probability of not getting the same number twice is
