Question

PLEASE HELP NOW!!! What would be the experimental probability of drawing a white marble?

Ryan asks 80 people to choose a marble, note the color, and replace the marble in Brianna's bag. Of all random marble selections in this experiment, 34 red, 18 white, 9 black, and 19 green marbles are selected. How does the theoretical probability compare with the experimental probability of drawing a white marble? Lesson 9-3

Answer 1

Answer: 18/80 for theoretical and then 18/80=.225 = 22.5% for experimental

Step-by-step explanation: theoretical: theres 18 white marbles, and then add up 34 + 18+9+19 to get 80. to get theoretical its number of favorable outcomes over total size of sample space, therefore 18 over 80

Experimental: divide 18/80 to get .225 then move decimal over by 2 to get 22.5%
