Question

Suppose you are choosing at random from the numbers 1 through 12 (inclusive). If the event E is "the number is even," find the set representing E. Express your answer as a bracketed set in the form {a,b,c,d}.

Answer 1

The set numbers from 1 to 12(inclusive) is:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

The set even numbers are:

2, 4, 6, 8, 10, 12

Given that the event E is "the number is even"

Therefore, the set representing the event E as a bracketed set is:

`E=\mleft\lbrace2,4,6,8,10,12\mright\rbrace`
