A certain insecticide kills 70% of all insects in laboratory experiments. A sample of 14 insects is exposed to the insecticide in a particular experiment. What is the probability that exactly 3 insects will survive? Round your answer to four decimal places.
p = 0.7
n = 14
P(X = x) = 14Cx * 0.7x * (1 - 0.7)14-x
P(3 insects will survive) = P(11 insects will die)
= (14C11 * 0.711 * 0.33)
= 0.1943
