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
Answer:
A
Step-by-step explanation:
