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
Find the theoretical probability of selecting a pink rubber band
You repeatedly choose a rubber band from the box record the color, and put the rubber band back in the box. Find the experimental probability of each color based on the table if pink had 36 occurrences and brown had 33
Theoretical probability of selecting a pink rubber band:
P(pink) = number of pink rubber bands / total number of rubber bands
P(pink) = 95 / (95 + 90)
P(pink) = 95/185
P(pink) = 19/37
Experimental probability of selecting a pink rubber band:
P(pink) = number of times pink was selected / total number of selections
P(pink) = 36 / (36 + 33)
P(pink) = 36/69
P(pink) = 12/23
Experimental probability of selecting a brown rubber band:
P(brown) = number of times brown was selected / total number of selections
P(brown) = 33 / (36 + 33)
P(brown) = 33/69
P(brown) = 11/23
