hey..
Total no.of possible outcomes = 132 + 12 = 144
No.of favourable outcomes = 132
P (E) = no.of favourable outcomes / total no.of possible outcomes
P (G) = 132/144
Total no.of possible outcomes = 132 + 12 = 144
No.of favourable outcomes = 132
P (E) = no.of favourable outcomes / total no.of possible outcomes
P (G) = 132/144

Number of good Pens = 132
Number of defective pens = 12
Total Number of pens = 144
Probability of a good pen = 132 /144
Number of defective pens = 12
Total Number of pens = 144
Probability of a good pen = 132 /144
