kaylee owns a small business selling clothing. she knows that in the last week 3 customers paid cash, 21 customers used a debit card, and 46 customers used a credit card. based on these results, express the probability that the next customer will pay with a debit card as a decimal to the nearest hundredth. answer attempt 1 out of 2

Answer

Explanation:

Step1: Calcular el número total de clientes

$3 + 21+46=70$

Step2: Calcular la probabilidad

La probabilidad de que un cliente pague con tarjeta de débito es el número de clientes que usaron tarjeta de débito dividido por el número total de clientes. Entonces, $\frac{21}{70}=0.30$

Answer:

$0.30$
