20 eggs are in a refrigerator, 2 are bad, from the 4 are chosen at random to make a cake what is the probability that exactly one egg is bad
Given
Total number of eggs in the refrigerator = 20
Number of bad eggs = 2
Number of good eggs = 20 - 2 = 18
P(=1)=4!3!0.110.93=0.29P(=1)=\frac {4!} {3!}0.1^10.9^{3}=0.29P(=1)=3!4!0.110.93=0.29
