Step-by-step Solution
Para calcular la probabilidad de que el próximo cliente pague con una tarjeta de crédito, primero sumamos el total de clientes:
Total de clientes = Clientes que pagaron en efectivo + Clientes que usaron tarjeta de débito + Clientes que usaron tarjeta de crédito
Total de clientes = 60 + 3 + 27 = 90
Ahora, la probabilidad de que el próximo cliente pague con tarjeta de crédito es el número de clientes que usaron tarjeta de crédito dividido por el total de clientes:
Probabilidad = (Clientes que usaron tarjeta de crédito) / (Total de clientes)
Probabilidad = 27 / 90
Ahora simplificamos la fracción. Ambos números son divisibles por 9:
27 ÷ 9 = 3
90 ÷ 9 = 10
Por lo tanto, la probabilidad de que el próximo cliente pague con tarjeta de crédito es:
**3/10**
Quick Answer
La probabilidad de que el próximo cliente pague con tarjeta de crédito es 3/10.
