7) Bumble bees travel to collect pollen as a food source for their entire colony 4 times in a day. A researcher studied 20 bumble bees and recorded the number of trips each bumble bee successfully returned to their colony with collected pollen out of the 4 trips that is makes. The data table is shown below. #trips pollen was collected 0 1 2 3 4 # bees 2 4 7 5 2 c) Calculate the binomial probability of a bee having less than 2 successful trips out of 4 trips.
