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.

To find the probability that the next customer will pay with a debit card, we need to calculate the total number of customers and then determine the proportion of those who paid with a debit card.<br /><br />Total number of customers = 3 (cash) + 21 (debit card) + 46 (credit card) = 70<br /><br />Probability of paying with a debit card = Number of customers who paid with a debit card / Total number of customers<br />= 21 / 70<br />= 0.3<br /><br />Therefore, the probability that the next customer will pay with a debit card is 0.3 or 30%.
