Exercício de Distribuição de Probabilidades
Como se resolve?
Um atirador dispara sobre um alvo. Em cada tiro, ele pode fazer um, dois ou três pontos. E cada tiro a probabilidade de fazer 3 pontos é 0.6. As restantes pontuações são igualmente prováveis. Certo dia ele disparou 500 tiros. Somaram-se os pontos obtidos. Qual foi, aproximadamente, a pontuação total?
