Question

Two eggs are drawn successively with replacement from a lot containing 10% defective eggs

Answer 1

Answer:

Step-by-step explanation:

For example there are total 100 eggs. From that 10% are defective means

100-100*(10/100)=90

From 90 two eggs successively drawn with replacement.

=2c2/90c2

=((2*1/1*2))/((90*89)/(1*2))

=1/(45*89)=1/4005
