A box contains 20 red balls, 25 white balls, and 55 blue balls. Suppose that 10 balls are selected at random one at a time with

replacement; that is, each selected ball is replaced in the box before the next selection is made. Determine the probability that at least one color will be missing from the 10 selected balls.

Answer:

0.164 = 16.4% probability that at least one color will be missing from the 10 selected balls.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Determine the probability that at least one color will be missing from the 10 selected balls.

Red missing:

Each time, there are 55 + 25 = 80 non-red balls, out of 100. So, in each of the 10 trials, 80% = 0.8 probability of not picking a red ball. The probability that no red ball is picked is given by:

(0.8)^10 = 0.1074

White missing:

55 + 20 = 75 non-white balls, out of 100, in each trial. The probability that no white ball is picked is given by:

(0.75)^10 = 0.0563

Blue missing:

45 non-blue balls, out of 100. The probability that no blue ball is picked is given by:

(0.45)^10 = 0.0003

Total:

0.1074 + 0.0563 + 0.0003 = 0.164

0.164 = 16.4% probability that at least one color will be missing from the 10 selected balls.

What is equivalent to 7/8+9/15
Xelga [282]

Answer:

Depends where the parenthesis are. But if you solve it using PEMDANS it's 1.475.

Step-by-step explanation:

When solving something like this, you use PEMDAS, sometimes known as GEMDAS and solve it in this order.

P/G=Parenthesis

E= Exponents

M= Multiplication

D= Division

A= Addition

S= Subtraction.

So skip P, E, M, and S because there are no parenthesis, exponents, multiplication, or subtraction signs.

So 7/8=0.875. 9/15=0.6, and if you add those you get 1.475

Need help figuring this equation 1/12c =.6
soldi70 [24.7K]
1/12c = 0.6

To remove a fraction you simply multiply it by its inverse fraction (take the original fraction and flip it! So, multiply it by 12/1 (which is the same as saying 12).

12(1/12c) = 0.6*12

The 12 cancels out leaving this: 

c  = 0.6 * 12
c = 7.2

If you don't have or are allowed to use a calculator. To compute that you simply make 0.6 into a fraction then multiply the numerator by 12. .6 is in the tenths place so you can write it like this: 
6/10 simplifying it becomes, 3/5

3/5 * 12 = 36/5

Now! That was assuming 1/12c was written like this: 
(1/12)c = 0.6

If it was actually written like this: 
1/(12c) = 0.6 then you'll do this. 

Multiply 0.6 by 12c. Which will get you 7.2c. After that you need to get c alone, so you divide both sides by 7.2. Yielding the result: 

1/7.2 = c 

c = 0.1389...

John has 3/8 ribbons. He gave his friends 2/6 to his friend. How many ribbons are left for him?
dybincka [34]

Answer:

1 / 24

Step-by-step explanation:

= > 3/8 - 2/6

=> {(3 x 3)/(8 x 3)} - {(2x4)/(6x4)}

=> 9/24 - 8/24

=> ( 9 - 8 ) / 24

= 1 / 24 ANS
