Sagot :
There are 2 bad bags out of 20, so the probability of bad bags is:
[tex] \frac{2}{20} = \frac{1}{10} = 0.1[/tex]
But we want the complement, which is the probability of bags which are not bad, and that is :
[tex]1-0.1=0.9[/tex]
D.) 0.9
A complement of an event is the opposite of what is happening. There are 2 bags out of 20 that are going bad. The complement would be 18 bags out of 20 because those are the amount of bags that are NOT going bad.
18/20= 9/10= 0.9
Complement just means opposite.
