I bought a car of 650,000 and<br>sold it for 520,000. Find the<br>lost Percent ?<br>​
Tom [10]

Answer:

20% decrease in value.

Step-by-step explanation:

Do 650,000 divided by 100 to find what 1% of the original price is:

650,000 divided by 100 = 6,500

To find what percentage of the original price 520,000 is, we divide it by 1% of the original cost (6,500):

520,000 divided by 6,500 = 80 (percent)

So if 520,000 is 80% of 650,000 the car has decreased in value by 20%.

The required probability for
a. 0.2058
b. 0.98  
c.0.016

<h3>
What is probability?</h3>

Probability can be defined as the ration of favorable outcomes to the total number of events.

Let use binomial distribution.
Probability answering a question correctly=1/3 =0.33
Probability of not answering a question correctly
=1–1/3
=2/3
a) Out of 10 probability of answering 4 correctly

=10c4 x (0.33)^4 x (0.66)^6

Upon simplification, 0.2058

b) Find the probability for getting at least 2 correct answers
= 1 - { 10c8 x (0.33)^8 x (0.66)^2+ 10c9 x (0.33)^9 x (0.66)^1 + (0.33)^10}
= 0.98

c).Find the probability for getting 2 or 3 incorrect answers.


10c8 x (0.33)^8 x (0.66)^2 + 10c7 x (0.33)^7 X (0.66)^3
=0.002 + 0.014

= 0.016

Thus the required probabilities are: 0.2058, 0.98 , 0.016
