Answer 1

Answer: (C)

$\frac{3}{5}$

One week before New Year, Joy sent 8 greeting cards to his friends in Delhi and 12 to his friends in Mumbai. If a card is picked randomly from the cards that were sent by him, the probability of picking a card which is not for a friend in Delhi $P\left(E\right)=\frac{lette{r}_{m}umbai}{tota{l}_{l}etter}=\frac{12}{20}=\frac{3}{5}$
