de acuerdo con los estudios de la maestra leticia la probabilidad de pasar el primer examen parcial es 0.8, mientras que la posibilidad de que aprueben el segundo es 0.6 y la que aprueben ambos es de 0.51 ¿cual es la probabilidad de que un alumno no apruebe ninugun examen parcial?

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
