Determine the sets of natural number
Represent this set with letter N
From definition of natural numbers, they are integer numbers starting from 1;
In other words: 1,2,3,4,5, and so on.
To represent this as a set of N, we have

<em>The ..... means that the counting still continues</em>
Li can expect to roll a one 4 times.
Since there are six possibilities (1, 2, 3, 4, 5 & 6), you divide 24 and 6 to get 4.
X = 16y^2 + 1
x - 1 = 16y^2
(x - 1)/16 = y^ 2
( (x-1) / 16 ) ^1/2 = y
( (x-1) ^ 1/2 ) / 4 = y
