Answer:

0.6

Step-by-step explanation:

La fórmula para calcular la probabilidad de dos eventos se da como:

P (A⋃B) = P (A) + P (B) - P (A ⋂ B)

De la pregunta, sabemos que:

Probabilidad de que Carlos haya comido pollo frito: P (C) = 0.4.

Probabilidad de que Carlos coma una hamburguesa para el almuerzo: P (H) = 0.3.

Probabilidad de que Carlos almorce pollo frito y hamburguesa el mismo día: P (C ⋂ H) = 0.1.

Probabilidad de que Carlos coma pollo frito o hamburguesa para el almuerzo:

P (C ⋃ H) =?

Por lo tanto, aplicando nuestra fórmula:

P (C ⋃ H) = P (C) + P (H) - P (C ⋂ H)

P (C ⋃ H) = 0.4 + 0.3 - 0.1

P (C ⋃ H) = 0.6
