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 6 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 3 outcomes in event A.

n(A)=3

(c)The probability of event A

[tex]P(A)=\dfrac{n(A)}{n(S)} =\dfrac{3}{6} =0.5[/tex]

P(A) =0.5 is the probability that you choose an even number.
