Probability and statistics , the branches of mathematics concerned with the laws governing random events, including the collection, analysis , interpretation, and display of numerical data. Probability has its origin in the study of gambling and insurance in the 17th century, and it is now an indispensable tool of both social and natural sciences. Statistics may be said to have its origin in census counts taken thousands of years ago; as a distinct scientific discipline , however, it was developed in the early 19th century as the study of populations, economies, and moral actions and later in that century as the mathematical tool for analyzing such numbers. For technical information on these subjects, see probability theory and statistics. The modern mathematics of chance is usually dated to a correspondence between the French mathematicians Pierre de Fermat and Blaise Pascal in

There are two types of random variables , discrete random variables and continuous random variables. The values of a discrete random variable are countable, which means the values are obtained by counting. All random variables we discussed in previous examples are discrete random variables. We counted the number of red balls, the number of heads, or the number of female children to get the corresponding random variable values. The values of a continuous random variable are uncountable, which means the values are not obtained by counting. Instead, they are obtained by measuring.

To find this probability, we need to transform the random variable p 1 - p 2 into a z-score. This problem requires us to find the probability that p 1 is less than p 2. Probability theory is based on some axioms that act as the foundation for the theory, so let us state and explain these axioms. Outside of work, Josh enjoys gardening, traveling, and playing board games with his family.

Si, senor, - засмеявшись, ответила Мидж с подчеркнутым пуэрто-риканским акцентом и, подмигнув Бринкерхоффу, направилась к двойной двери директорского кабинета. Личный кабинет Лиланда Фонтейна ничем не походил на остальные помещения дирекции. В нем не было ни картин, ни мягкой мебели, ни фикусов в горшках, ни антикварных часов.

До поворота еще минуты две. Он знал, что этого времени у него. Сзади его нагоняло такси. Он смотрел на приближающиеся огни центра города и молил Бога, чтобы он дал ему добраться туда живым.
