Question

In a bundle of $50$ shirts, $44$ are good, $4$ have minor defects and $2$ have major defects. What is the probability that it is acceptable to a trader who accepts only a good shirt?

Answer 1

We have,

Total number of shirts $=50$

Total number of elementary events $=50=n\left(S\right)$

As, trader accepts only good shirts and number of good shirts $=44$

Event of accepting good shirts $=44=n\left(E\right)$

Probability of accepting a good shirt $=n\left(E\right)/n\left(S\right)=44/50=22/25$
