Show your !     brainiest for first right answer!   instructions: 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 .

Hello there! :D 

Part A: There are five buttons in all in the given item. The item can be answered through the fundamental principles of counting.

There are 5 items to choose from during the first pick... Because the shape can be be returned and picked again, there are also 5 items to choose from in the second pick. Multipying them ,
N=5x5=25

Therefore, the sample side for the compound event is equal to 25. 

Part B: The same concept can be used in this part of  them item; however, instead of 5 there are 6 buttons to choose from.

N=6x6=36

Hence, the sample size of this picking process is 36! :

Hoped this helped you friend! :D
