Show that any positive odd integer is of the form 6q+1 or 6q+3 or 6q+5, where q is some integer.

Let a be any positive odd integer, we apply the division algorithm with a and b = 6.
Since 0≤r<6, the possible remainders are 0, 1, 2, 3, 4 and 5. i.e., a can be 6q or 6q + 1, or 6q + 2, or 6q + 3, or 6q +4, or 6q +5 where q is quotient.

However, since a is odd

∴a cannot be equal to 6q,6q+2,6q +4

∵All are divisible by 2

Therefore, any odd integer is of the form 6q+1 or 6q+ 3 or 6q+5.

What is circumference of a circle?

The total length of boundary of a circle is called circumference of a circle.
Circumference of a circle = 2πr; where 'r is radius of the circle.

What is an event in Probability?

The collection of some or all possible outcomes of a random experiment is called an event

What is an impossible event in Probability?

An event associated with random experiment is called an impossible event. If it never occurs when every experiment is performed.
