Let's assume there are 100 customers.
Out of those 100 customers, 60% will use the pick-up and delivery service, which means 60 customers will use it.
Out of those 100 customers, 60% will also use the account service, which means 60 customers will use it.
Now, we need to find the probability that a customer will use both services.
Since there are 60 customers using the pick-up and delivery service, and we need to find the probability that a customer will use both services, we can assume that those 60 customers are the only ones who can use both services.
Therefore, the probability that a customer uses both services is: 
(Number of customers who use both services) / (Total number of customers) 
= 60/100 
= 0.6 
So the answer is C) 0.36
