Hi! I'm wondering which distribution I should utilize for the situation below. or should I use percentiles? Thank you!

In order to minimize the occurrence of money laundering, certain nancial companies are required to conduct small background checks on their customers before accepting money from them. under the so-called Anti Money Laundering (AML) laws. When a customer makes a payment to an organization operating under AML laws, the money is transferred to the organization but suspended for a brief holding period while a background check is conducted on the customer. Typically, nancial companies outsource the background check process to a third- party AML provider. 3. Say an AML provider claims that their background checks typically require a holding period of no more than 5 days. If this is true. what percentage of their background checks will be completed within 3 days? (regardless of background check's outcome)
