Answer:
(27/36) = (3/4) = 0.75
Step-by-step explanation:
The complete question is attached to this solution.
P(9 or fewer boxes) = P(x ≤ 9)
Since Vera carried out the simulation/experiment, this probability will be read from the results of her simulation (the dotplot).
Note that the dots on the numbers of the dotplot represent the number of boxes it took Vera to get all the prizes.
So, the probability of getting all the prizes in 9 or fewer boxes will be just counting the number of times in the simulation where she got the 4 prizes in 9 boxes or fewer.
This starts from the least number on the dotplot, 4 all the way to 9.
Total number of simulations = 36
P(x ≤ 9) = P(x=4) + P(x=5) + P(x=6) + P(x=7) + P(x=8) + P(x=9)
= (4/36) + (6/36) + (3/36) + (4/36) + (4/36) + (6/36) = (27/36)
Hope this Helps!!!!
