2. The scale is 3 inches = 2 feet.

Divide total inches by 3, then multiply by 2:

30 / 3 = 10

10*2 = 20 feet.

3. Divide the 9cm by 3cm, then multiply by 8 km

9/3 = 3

3*8 = 24 kilometers.

4. Divide real distance by distance on map:

36 / 4 = 9

1 inch = 9 miles

5. Divide real dimension by the drawing dimension:

21 meters / 3 centimeters = 7

1 cm = 7 meters

The probability that an electronic device produced by a company does not function properly is equal to 0.1. If 10 devices are bo

Answer:

Correct option: A. P=0.057

Step-by-step explanation:

<u>Binomial Distribution</u>

The binomial distribution fits the case of n independent events each one with a probability of success equal to p where k successes have been achieved.

The PMF (Probability Mass Function) of the binomial distribution is

$\displaystyle P(k,n,p)=\binom{n}{k}p^kq^{n-k}$

Where $q = 1-p$

The individual probability that an electronic device does not function properly is p=0.1. We know n=10 devices have been bought and we want to compute the probability that 7 devices function properly. Please notice that this is not the value of k since p is the probability of failure. The correct value of k=10-7=3. The required probability is

$\displaystyle P(3,10,0.1)=\binom{10}{3}0.1^30.9^{10-3}$
