<h3>What is natural selection?</h3>

Natural selection is a term that refers to the evolutionary process that is based on the principle that establishes the survival of the fittest or the preponderance of the law of the strongest in a natural environment without external intervention.

In natural selection, the least fit or weakest individuals perish and their traits are not transmitted to the following generations by not reproducing.

According to the above, it can be inferred that the traits of the weak or less fit organisms studied four years earlier were not transmitted to the following generations, so the organisms studied by Losos four years later are not the same, but the offspring of The originals.

The access code for a card security system consist of four digits the first digit cannot be 4 and the last digit must be odd. Ho

Deffense [45]

Different codes for access code which are available are: 4000

_ _ _ _

1 2 3 4

1st blank can be filled with the following possibilities, here the conditions are:

1)The first digit cannot be 4

2)The first digit cannot be 0 also since it makes the access code 3 digits hence

From 1 to 9 except 4 there are 8 possible ways to fill that blank

2nd blank can be filled with any number between 0 to 9 in 10 possible ways

3rd blank can be filled with any number between 0 to 9 in 10 possible ways

4th blank can be filled with any odd numbers between 0 to 10 - 1,3,5,7,9

<u>8</u> <u>10</u> <u>10</u> <u>5</u> = 8 x 10 x 10 x 5 = 4000

Hence to conclude that 4000 available codes are there for the access security card
