This statement is not true.
If a number is whole number, it will not always be a natural number. An example of a whole number that is not a natural number is 0. Think of natural numbers as counting number so 1, 2, 3, 4, ... and so on. Whole numbers are natural numbers but they also include 0. When we count up, we usually don’t starts with 0 so it’s not a natural number but it is a whole number.
Therefore, if a number is a whole number, it does not necessarily have to be a natural number.

Answer:
12 milk chocolates.
Step-by-step explanation:
-We know that probabilities add upto 1:
Let X be the total number of chocolates. We know that probability is the successful events divided by the total number of events:
#We subtract the number of dark chocolates from X to get the number of milk chocolates:
Hence, there must be 12 milk chocolates.
Let a, b be two odd integers. Then both can be written as
a=2k-1, k is an integer
b=2m-1, m is an integer
So,
a-b=2k-1-(2m-1)=2k-2m-2=2(k-m-1)
Since, k and m and 1 are all integers, then (k-m-1) is also an integer. Hence, 2(k-m-1) is an even integer.
Thus, a-b is even.
