Answer

Explanation:

Step1: Calcular el número total de clientes

Sumamos el número de clientes que pagaron de diferentes maneras. $70 + 20+22=112$ clientes

Step2: Calcular el número de clientes que no pagaron con débito

Sumamos el número de clientes que pagaron en efectivo y con crédito. $70 + 22 = 92$ clientes

Step3: Calcular la probabilidad

Dividimos el número de clientes que no pagaron con débito entre el número total de clientes y multiplicamos por 100 para obtener el porcentaje. $P=\frac{92}{112}\times100=\frac{9200}{112}\approx82.14$

Step4: Redondear al número entero más cercano

Redondeamos 82.14 al entero más cercano, que es 82.

Answer:

82%
