Errol is looking for a partner to participate in a quiz competition. he is choosing from among six of his classmates. which simulation can errol use to randomly make his selection?
a. flipping a coin
b. rolling a six-sided die
c. spinning a spinner divided into twelve sections
d. picking a card from a suit of cards

Options B and C

Step-by-step explanation: Now we have 6 possible classmates, so we need an experiment that has 6 or a multiple of 6 possible options.

The ones that meet this condition are option b:

He can assign each number from 1 to 6 to a different classmate, then he can roll the die and by looking at the number, he can choose the classmate.

Option C: will be almost the same, but now we have 12 sections, so he can assign 2 sections to each classmate, and if he rolls it and selects the section that ends facing him, the classmate assigned to that section will be the chosen one.

For the other two cases, the simulation can not be done, because a coin only has 2 options and a pick of cards has 52 options, that is not a multiple of 6
