Question

Lucas has five buttons in a container. Each button is a different shape. There is a star, an oval, a hexagon, a circle, and a heart. He picks one button, replaces it, and then picks another button. The sample size for this compound event is__ . Suppose one square-shaped button is added to the container. If Lucas repeats the same picking process, then the sample size would be__ .

Answer 1

Contains 5 buttons...
picks one, then replaces. then picks another

since he puts the button back, the sample size remains the same as when he picked the 1st one....and that sample size is 5

if 1 button is added, and he uses the same process and replaces the button he picked, then the sample size will be 6....because 1 button was added making a total of 6 buttons.
