Answer:
Hence, the probability of the complement of rolling a number less than 5 by using a six-sided die is:
1/3
Step-by-step explanation:
Let A denote the event of rolling a number less than 5 in a six-sided die.
Now, we know that the Total outcomes are: 6
since, the sample space is given as: {1,2,3,4,5,6}
Also Number of favorable outcomes are: 4
since the numbers which are less than 5 are {1,2,3,4}
Now we have to find:
[tex]P(A^c)[/tex]
where P denotes the probability of an event and [tex]A^c[/tex] denote the complement of event A.
We know that:
[tex]P(A^c)=1-P(A)[/tex]
Now,
[tex]P(A)=\dfrac{4}{6}\\\\P(A)=\dfrac{2}{3}[/tex]
Hence,
[tex]P(A^c)=1-\dfrac{2}{3}\\\\P(A^c)=\dfrac{3-2}{3}\\\\P(A^c)=\dfrac{1}{3}[/tex]
Hence, the probability of the complement of rolling a number less than 5 by using a six-sided die is:
1/3
