E) A set of 75 chips in which 15 chips are black and the remainder are red

Answer 1

Simulation methods that could be used to model the different types of payment include a spinner with 5 equal sections and a set of 75 chips in which 15 chips are black and the remainder are red.

Step-by-step explanation:

To simulate the different types of payment, the shop owner can use the following simulation methods:

• A spinner with 5 equal sections (C): The spinner can have 1 section for cash and 4 sections for credit card, representing the 20% cash payment and 80% credit card payment.
• A set of 75 chips in which 15 chips are black and the remainder are red (E): The black chips can represent the cash payments, while the red chips can represent the credit card payments.
