Answer:
(a)6 (b)3 (c)0.5
Step-by-step explanation:
Given a fair die with the numbers 1,2,3,4,5, or 6 on each of its faces.
- Event A is the event of rolling an even number
- Event B is the event of rolling an odd number.
(a)The sample space for the outcomes in this experiment is {1,2,3,4,5,6}
There are <u>6</u><u> </u>outcomes in the sample space.
n(S)=6
(b)
Event A is the event of rolling an even number
Sample space of A = {2,4,6}
There are <u>3</u> outcomes in event A.
n(A)=3
(c)The probability of event A
P(A) =<u>0.5</u> is the probability that you choose an even number.
