Olivia owns a small business selling bagels. She knows that in the last week 11 customers paid cash, 78 customers used a debit card, and 3 customers used a credit card. Based on these results, express the probability that the next customer will pay with a debit card or a credit card as a decimal to the nearest hundredth. Answer:

Calculate Total Customers: Determine the total number of customers from last week. Total customers = Customers who paid cash + Customers who used a debit card + Customers who used a credit card Total customers = 11 (cash) + 78 (debit card) + 3 (credit card) Total customers = 92Calculate Debit or Credit Customers: Calculate the number of customers who paid with a debit card or a credit card. Customers who used a debit card or credit card = Customers who used a debit card + Customers who used a credit card Customers who used a debit card or credit card = 78 (debit card) + 3 (credit card) Customers who used a debit card or credit card = 81Calculate Probability: Calculate the probability that the next customer will pay with a debit card or a credit card. Probability = (Customers who used a debit card or credit card) / (Total customers) Probability = 81 / 92 Probability ≈ 0.8804347826086957Round Probability: Round the probability to the nearest hundredth. Rounded probability = 0.88

Q. Olivia owns a small business selling bagels. She knows that in the last week

11

customers paid cash,

78

customers used a debit card, and

3

customers used a credit card.

\newline

Based on these results, express the probability that the next customer will pay with a debit card or a credit card as a decimal to the nearest hundredth.

\newline

Answer:

Calculate Total Customers: Determine the total number of customers from last week. $\newline$ Total customers $= \text{Customers who paid cash} + \text{Customers who used a debit card} + \text{Customers who used a credit card}$ $\newline$ Total customers $= 11 \text{ (cash)} + 78 \text{ (debit card)} + 3 \text{ (credit card)}$ $\newline$ Total customers $= 92$
Calculate Debit or Credit Customers: Calculate the number of customers who paid with a debit card or a credit card. $\newline$ Customers who used a debit card or credit card $= \text{Customers who used a debit card} + \text{Customers who used a credit card}$ $\newline$ Customers who used a debit card or credit card $= 78 \text{ (debit card)} + 3 \text{ (credit card)}$ $\newline$ Customers who used a debit card or credit card $= 81$
Calculate Probability: Calculate the probability that the next customer will pay with a debit card or a credit card. $\newline$ Probability = (Customers who used a debit card or credit card) / (Total customers) $\newline$ Probability = $\frac{81}{92}$ $\newline$ Probability $\approx 0.8804347826086957$
Round Probability: Round the probability to the nearest hundredth. $\newline$ Rounded probability = $0.88$
