Question

bilquis owns a small business selling used books. she knows that in the last week 49 customers paid cash, 42 customers used a debit card, and 32 customers used a credit card. based on these results, express the probability that the next customer will pay with a credit card as a decimal to the nearest hundredth.

Explanation:

Step1: Calculate total number of customers

Add the number of customers who paid cash, used a debit card, and used a credit card.
$49 + 42+32=123$

Step2: Calculate probability of customer paying with credit card

Probability formula is $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, number of favorable outcomes (customers using credit card) is $32$, and total number of outcomes (total customers) is $123$.
$P=\frac{32}{123}\approx0.26$ (rounded to the nearest hundredth)

Answer:

$0.26$
