Answer 1

Answer:

$0$

Step-by-step explanation:

It is said that $2%$% of the items in a factory are defective.

⇒ For a $100$ items, the number of defects = $\frac{2}{100} *100$ = $2$ items

∴ The probability of finding $3$ defects in a box of $100$ items is $0$ as there can only be $2$ defective items possible.
