A population of 80 rats is tested for 4 genetic mutations after exposure to some chemicals: mutation A, mutation B, mutation C, and mutation D. 43 rats tested positive for mutation A. 37 rats tested positive for mutation B. 39 rats tested positive for mutation C. 35 rats tested positive for mutation D. One rat tested positive for all four mutations. 5 rats tested positive for mutations A, B, and C. 4 rats tested positive for mutations A, B, and D. 6 rats tested positive for mutations A, C, and D. 3 rats tested positive for mutations B, C, and D. 64 rats tested positive for mutations A or B. 63 rats tested positive for mutations A or C. 59 rats tested positive for mutations A or D. 58 rats tested positive for mutations B or C. 59 rats tested positive for mutations B or D. 60 tested positive for mutations C or D. 8 rats did not show any evidence of genetic mutation. What is the probability that if 5 rats are selected at random, 3 will have exactly 2 genetic mutations?

Question
A population of 80 rats is tested for 4 genetic mutations after exposure to some chemicals: mutation A, mutation
B, mutation C, and mutation D. 43 rats tested positive
for mutation A. 37 rats tested positive for mutation B. 39 rats tested positive for mutation C. 35 rats tested positive
for mutation D. One rat tested positive for all four
mutations. 5 rats tested positive for mutations A, B, and C. 4 rats tested positive for mutations A, B, and D. 6 rats
tested positive for mutations A, C, and D. 3 rats tested
positive for mutations B, C, and D. 64 rats tested positive for mutations A or B. 63 rats tested positive for
mutations A or C. 59 rats tested positive for mutations A or D.
58 rats tested positive for mutations B or C. 59 rats tested positive for mutations B or D. 60 tested positive for
mutations C or D. 8 rats did not show any evidence of
genetic mutation.
What is the probability that if 5 rats are selected at random, 3 will have exactly 2 genetic mutations?
Round your answer to five decimal places.
