En qué se diferencia la natalidad en los países más desarrollados frente alos países menos desarrollados..

En general, se puede afirmar que los países subdesarrollados son los que tienen unas tasas de natalidad más altas. Así, en conjunto los países subdesarrollados alcanzan una tasa de natalidad del 34 por 1.000, mientras que la correspondiente al grupo de los países desarrollados es de sólo un 16 por 1.000.

Step-by-step explanation:

For each name, there are only two outcomes. Either the name is authentic, or it is not. So, we can solve this problem using the binomial probability distribution.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.

And is the probability of X happening.

In this problem.

5 names are selected, so

A success is a name being non-authentic. 40% of the names are non-authentic, so .

We have to find

Either the number of non-authentic names is 0, or is greater than 0. The sum of these probabilities is decimal 1. So:

So
