Question

Suppose x coins are tossed. Write an expression to represent the number of possible outcomes.

Answer 1

1/2

Answer 2

2x

Answer 3

each time you have a possibility of 2 results. Therefore, you have the number of results of the action times the number of times the action is done.

Answer 4

number of outcomes "multiplies" by two each time, so total number of outcomes would be:\[2^x\]
