A. Find the theoretical probability of selecting a pink rubber band
B. Find the theoretical probability of selecting a brown rubber band
C. You repeatedly choose a rubber band from the box, record the color, and put the rubber band back in
the box. The results are shown in the table below. Find the experimental probability of each color
based on the table.
Pink
36
Brown
33
I'm not totally sure but here is what I think.
prob(pink) = 36/69 = 12/23
prob(brown) = 33/69 = 11/23
comparing:
theoretical prob(pink) = .5125..
experimental prob(pink) = .5217
A box contains 95 pink rubber bands and 90 brown rubber bands. You select a rubber band at random
from the box. Find each probability. Write the probability as a fraction in simplest form.
a. Find the theoretical probability of selecting a pink ribber band.
b. Find the theoretical probability of selecting a brown rubber band.
c. You repeatedly choose a rubber band from the box, record the color, and put the rubber band back in
the box. The results are shown in the table below. Find the experimental probability of each color
based on the table.
Outcome Occurrences
Pink 36
Brown. 33
I missed some info
Total Bands: 69
A. The theoretical probability of selecting a pink rubber band is 36/69.
B. The theoretical probability of selecting a brown rubber band is 33/69.
C. table is not shown so I cannot answer the question.
To find the theoretical probability of selecting a pink rubber band, you need to know the total number of rubber bands in the box and the number of pink rubber bands. Without that information, we cannot calculate the theoretical probability.
To find the theoretical probability of selecting a brown rubber band, similarly, you need to know the total number of rubber bands in the box and the number of brown rubber bands. Without that information, we cannot calculate the theoretical probability.
To find the experimental probability of each color based on the table provided, you need to divide the number of times each color occurred by the total number of trials. In this case, the number of times pink occurred is 36, and the number of times brown occurred is 33. However, we still need to know the total number of trials (the total number of rubber bands chosen) in order to calculate the experimental probabilities accurately.
