To find the probability of the next customer paying with a debit card or credit card, we need to add the number of customers who used a debit card to the number of customers who used a credit card and divide by the total number of customers:
Probability = (number of debit or credit customers) / (total number of customers)
Probability = (25 + 24) / (19 + 25 + 24)
Probability = 49 / 68
Probability ≈ 0.72
Expressing this as a decimal to the nearest hundredth, we get:
Probability ≈ 0.72 (rounded to two decimal places)
Peyton knows that in the last week 19 customers paid cash,25 customers used a debit card and 24 customers used a credit card. Express the probability that the next customer will pay with a debit card or credit card as a decimal to the nearest hundredth
