Falemos de Probabilidade

Falemos de Probabilidade

Abstract

Já disseste ou ouviste alguém dizer que “é provável que vá chover”, ou “não tenho sorte no jogo”. Palavras como provável, possibilidade, ou sorte, fazem parte do nosso quotidiano, revelando que todos temos uma noção de probabilidade. Mas o que é a probabilidade? Podemos dizer que ela mede o grau de possibilidade ou o grau de credibilidade de acontecimentos incertos se realizarem. E como medir o grau de possibilidade? A resposta definitiva só foi dada em 1933 quando Andrey Kolmogorov (1903-1987) propôs três regras para a correta atribuição de probabilidade. Com base nelas estabelece-se que a probabilidade é um número real entre 0 e 1, abrindo-se também portas para diferentes conceitos de probabilidade.
