type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar(s). 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

Explanation:

Step1: Define sample - size concept

Sample size is number of observations.

Step2: Analyze the picking process

Lucas picks one button, replaces it and picks another. Each pick is an observation. Since he makes 2 picks (first pick and second pick), the sample size for the compound event (the two - pick process) is 2.

2
