If you choose one person from the group, you have a 12/20 chance of them being a girl. Now, if the first person is a girl, we have one less girl and one less person to choose from. So, the new probability for the second person is 11/19.
Then, we multiply the chances
12/20 * 11/19
3/5 * 11/19
33/95
The different types of numbers include:
- Integers
- Rational numbers.
- Irrational numbers.
<h3>How o illustrate the information?</h3>
Integers are made up of both positive and negative numbers. There is neither a decimal nor a fractional part to any integer; instead, they are all represented by the letter Z.
An integer that is not negative and is always bigger than zero called a natural number. The letter N is used to symbolize it. Whole numbers don't have a decimal or fractional component, it should be stated.
The form p/q, where q is not equal to zero, is used to indicate a rational number, denoted by the symbol Q. All rational numbers, including integers, fractions, decimals, whole numbers, and natural numbers. Some examples of rational numbers include 1/2 and - 4/5.
The numbers that cannot be expressed using integers in the p/q form are now referred to as irrational numbers.

The question is wrong since population is not counted in points . for question like these use formula :P(1+R/100)^t where p is current population,r is rate and t is time.
