After having observed the contents and resources provided on the platform. Develop the
next workshop of introduction to probabilities
Workshop of a car company employees are classified in three divisions: Administration,
operation of plant and sales. The following table shows the number of employees in each
division, classified by sex:
With the information in the table, and if you pick randomly an employee;
What is the probability of being female?
the probability would be: 180/400 = 0,45 = 45%
What is the probability that work in sales?
the probability would be:150/400=0,375 =37,5%
What is the probability that either man and work in the sales division?
the probability would be:50/150 =0,333 =33,3%
What is the probability of being female if you are working in the division of plant
operation?
the probability would be: 60/200 = 0,3 =3%
They are the V and H statistically independent events: Events V and H are not
independent, since the result of a second effect is affected by the existence of the
first, that is, the probability of sales personnel is determined by gender as well as
quantity.
