Question

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 1

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.Total number of customers = 3 (cash) + 21 (debit card) + 46 (credit card) = 70Probability of paying with a debit card = Number of customers who paid with a debit card / Total number of customers= 21 / 70= 0.3Therefore, the probability that the next customer will pay with a debit card is 0.3 or 30%.
