The tables shows the sizes and colors of t shirts sold over the past week, to the nearest percent what is the experimental probability that the next customer who buys a t-shirt at the store will buy a large blue t-shirt? explain how you solved that problem
small medium large
white 32 49 28
blue 12 36 20
black 20 42 23

Probability is defined as the fraction, where the numerator is the number of favorable events (in this case number of large blue t-shirts, which is 20 in the table) and the denominator is the number of ALL possible events (in this example it is the sum of all sold t-shirts, when you sum up all the data in the table, you get total of 262 t-shirts).
So, probability that the next t-shirt (large blue) to be sold is:
P = 20/262 = 0.076335877
which is approximately 0.08 (when rounding to 2 decimal places).
We obtain the percentage of large blue t-shirt being sold next:
P = 8%
