Answer:
The probability that exactly 10 insects will die
P( X = 10 ) = 0.06385
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given a certain insecticide kills 60% of all insects in laboratory experiments
Given proportion p = 0.60
q = 1 - 0.60 = 0.40
Given sample size 'n' = 12
<u><em>Step(ii):</em></u>-
Let "X' be the random variable of binomial distribution

The probability that exactly 10 insects will die



<u><em>Final answer:</em></u>-
The probability that exactly 10 insects will die
P( X = 10 ) = 0.06385
