[justify]A teoria da probabilidade é o campo da Matemática que estuda experimentos ou fenômenos aleatórios e através dela é possível analisar as chances de um determinado evento ocorrer.[br]Quando calculamos a probabilidade, estamos associando um grau de confiança na ocorrência dos resultados possíveis de experimentos, cujos resultados não podem ser determinados antecipadamente. Probabilidade é a medida da chance de algo acontecer.[br]Desta forma, o cálculo da probabilidade associa a ocorrência de um resultado a um valor que varia de 0 a 1 e, quanto mais próximo de 1 estiver o resultado, maior é a certeza da sua ocorrência.[br]Por exemplo, podemos calcular a probabilidade de uma pessoa comprar um bilhete da loteria premiado ou conhecer as chances de um casal ter 5 filhos, todos meninos.[/justify]

[justify]Um experimento aleatório é aquele que não é possível conhecer qual resultado será encontrado antes de realizá-lo.[br]Os acontecimentos deste tipo quando repetidos nas mesmas condições, podem dar resultados diferentes e essa inconstância é atribuída ao acaso.[br]Um exemplo de experimento aleatório é jogar um dado não viciado (dado que apresenta uma distribuição homogênea de massa) para o alto. Ao cair, não é possível prever com total certeza qual das 6 faces estará voltada para cima.[/justify]

[justify]Em um fenômeno aleatório, as possibilidades de ocorrência de um evento são igualmente prováveis.[br]Sendo assim, podemos encontrar a probabilidade de ocorrer um determinado resultado através da divisão entre o número de eventos favoráveis e o número total de resultados possíveis:[br][br][img
