Explanation:

Step1: Calculate total number of customers

$3 + 21+46=70$

Step2: Calculate probability of customer using debit - card

The probability $P$ that a customer uses a debit card is the number of customers who used a debit card divided by the total number of customers. So $P=\frac{21}{70}=0.30$

$0.30$
