Is 0 an integer?

<p>Well the question says it all!</p>

<p>basically there was this question:</p>

<p>A list consists of different integers. If a number is to be chosen at random from the list, the probability that the number chosen will be odd is 1/3. What is the probability that the number chosen will be even?
a) 1/4
b) 1/3
c) 1/2
d) 2/3
e) 3/4</p>

<p>i thought that the answer would be 1/3 since the probability for even is 1/3, probability that the number is 0(that is if it is an integer) would be 1/3 and so probability for even numbers would be 1/3.</p>

<p>however the correct answer is 2/3...does that mean that 0 is not an integer???</p>

<p>someone please help!!</p>

<p>0 is an integer, but not an even number, bahahahahaha</p>

3

<p>Actually, 0 is an even integer, but it is neither negative nor positive.</p>

<p>Also, where is the list the question is talking about? Maybe you miscalculated something.</p>

4

<p>SirWanksalot is correct.
Zero is an even integer.</p>

5

<p>the list hasnt been given in the question! </p>

<p>so 0 is an even integer?</p>

6

<p>Yes, since 0 is an even integer, every other integer on that list would be even integers.
1 - 1/3 = 2/3</p>

7

<p>Here is a rigorous explanation as to why 0 is even:</p>

<p>Definition: An integer n is even if there is another integer k such that n = 2k.</p>

<p>For example:</p>

<p>6 is even because 6 =2*3.
-18 is even because -18 = 2(-9)</p>

<p>0 is even because 0 = 2*0.</p>

8

<p>If 1/3 is the probability for a number to be odd (3 out of 9) whatever numbers are left in the list are even and those are the rest 2/3 (the other 6 numbers)</p>

<p>Yeh two is zero I read some logic about it on wikipedia its pretty interesting.</p>

Read this its pretty interesting.

<p>Integers can be odd or even. </p>

<p>If 1/3 are odd, 2/3 are even.</p>
