In a rolling of standard die, the probability that 2 will not appear on the die is 5/6 or 0.833.
What is probability?
Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
The probability of event to be failure is one minus the probability of its success.
Given information-
The total number of time the die rolled is 1.
The probability of number 2 is not appear has to be find out.
The total number of outcome in a standard die is 6. Thus we have total 6 outcome. To find probability of number 2 is not appear, first find the probability of number 2 appears.
From the 6 outcome, have one favorable outcome of number 2. Thus the probability of number 2 appears, is,
[tex]P=\dfrac{1}{6}[/tex]
Thus the probability of number 2 appears is 1/6.
The probability of event to be failure or not occur is one minus the probability of its success. Thus, the probability of number 2 does not appear is,
[tex]P^{-1}=1-\dfrac{1}{6}\\P^{-1}=\dfrac{5}{6}[/tex]
Thus in a rolling the standard die, the probability that 2 will not appear on the die is 5/6 or 0.833.
