Carl has a drawer full of unmatched socks that are either black or blue. He is curious about
the probability of pulling two random socks from the drawer and getting a matching pair.
He does the experiment five times, returning the socks to the drawer between trials.
His results are recorded in the table below. Carl plans to conduct an additional 50 trials of
this same experiment. Based on the data in the table, how many times will he pull an
inmatched pair of socks?
Trial Number 1 2 3 4 5
