Question
22 defective pens are accidentally mixed with 136 good
ones. It is not possible to just look at a pen and tell whether or not it is defective. One pen is taken out at random from this lot. Determine the probability that the pen is taken out is a good one.Solution
Numbers of pens = Numbers of defective pens + Numbers of good pens ā“ Total number of pens = 136 + 22 = 158 pens P(E) = (Number of favourable outcomes) / (Total number of outcomes) P(picking a good pen) = 136/158 = 0.860
