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 the simplest form.
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.
Please explain how you got the answer

Best ResponseYou've already chosen the best response.1\[\large P(pink)=\frac{number\ of\ pink\ bands}{toal\ number\ of\ bands}\] You then need to see if the fraction can be simplified.

Best ResponseYou've already chosen the best response.1Good work! You are correct. P(brown) = (total number of brown) / (total number of bands)

Best ResponseYou've already chosen the best response.1Correct again! For part C, find the total number of occurrences ( pink + brown). The experimental probabilities are: P(pink) = (number of pink occurrences) / (total number of occurrences) P(brown) = (number of brown occurrences) / (total number of occurrences)

Best ResponseYou've already chosen the best response.069 total occurrences 36/69 33/69 Are occurrences the amount of times the rubber bands were picked out?
