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
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)
To find the probability of the next customer paying with a debit card or credit card, we need to determine the total number of customers who paid with either a debit card or credit card.
Total customers who paid with debit card = 25
Total customers who paid with credit card = 24
Adding these two numbers together:
Total customers who paid with debit or credit card = 25 + 24 = 49
Now, we can calculate the probability of the next customer paying with a debit card or credit card by dividing the total number of customers who paid with debit or credit card by the total number of customers:
Probability = (Number of customers who paid with debit or credit card) / (Total customers)
Probability = 49 / (19 + 25 + 24) = 49 / 68 ≈ 0.72 (rounded to the nearest hundredth)
Therefore, the probability that the next customer will pay with a debit card or credit card is approximately 0.72.
