There are 10 rolls of film in a box and 3 are defective. Two rolls are to be selected without replacement. What is the probabili
jarptica [38.1K]

Answer:   \dfrac{1}{15}

Step-by-step explanation:

Given : Total rolls of film in the box = 10

Defective rolls =3

Probability of selecting first defective roll = \dfrac{\text{Number of bad rolls}}{\text{Total rolls}}

=\dfrac{3}{10}

Now , total rolls left = 9

Total defective rolls left = 2

Probability of selecting second defective roll = \dfrac{\text{Number of bad rolls}}{\text{Total rolls}}

=\dfrac{2}{9}

Now , the probability of selecting a defective roll followed by another defective roll = \dfrac{3}{10}\times\dfrac{2}{9}=\dfrac{1}{15}

Hence, the probability of selecting a defective roll followed by another defective roll is \dfrac{1}{15} .

There are 100 cm to 1 meter,  so 1 square meter = 100^2 = 10,000 cm^2.

Therefore 1.92 m^2 = 10,000 * 1.92 =  19,200 cm^2.
