A certain insecticide kills 60% of all insects in laboratory experiments. A sample of 7 insects is exposed
to the insecticide in a particular experiment. What is the probability that exactly 5 insects will die?
Round your answer to four decimal places.

It is the binomial type probability distribution.
The number of trials n= 7; the probability of the success trial is 0.6, and the number of success trials k = 5.
P = = = 0.2613 (rounded). ANSWER
