Tanisha owns a small business selling bagels. She knows that in the last week 61 customers paid cash, 5 customers used a debit card, and 45 customers used a credit card. Based on these results, express the probability that the next customer will pay with cash as a decimal to the nearest hundredth
There were a total of 61 + 5 + 45 = 111 customers.
The probability of the next customer paying with cash is the number of customers who paid with cash divided by the total number of customers:
P(cash) = 61/111
Using a calculator, this simplifies to 0.55. Rounded to the nearest hundredth, the probability of the next customer paying with cash is 0.55.
Therefore, the answer is 0.55.
To find the probability that the next customer will pay with cash, we need to divide the number of customers who paid with cash by the total number of customers.
Total number of customers = number of customers who paid with cash + number of customers who used a debit card + number of customers who used a credit card
Total number of customers = 61 + 5 + 45
Total number of customers = 111
Probability of paying with cash = number of customers who paid with cash / total number of customers
Probability of paying with cash = 61 / 111
Dividing 61 by 111, we get the probability of paying with cash as approximately 0.55.
Therefore, the probability that the next customer will pay with cash, expressed as a decimal to the nearest hundredth, is 0.55.
