we need to find the probability of bad sound cards.

we are having 1000 computers so 1000 sound card will be there.

manager found that 4 sounds are defective out of 1000 sound cards.

$P(D)$ of defective sound cards= $n(D)/n(s)=4/1000=0.004$

we know that 1 is the total probability.out of 0.004 is the failure.
