You have a pot with 100 balls. 20 of them are red, 50 are blue and 30 are green. you decide to draw 5 balls from the pot without

replacement (i.e. you don't put a ball back in the pot once it has been taken out). what is the probability of drawing five blue balls?

The probability of drawing exactly 5 blue balls is found as follows:
P(5 blue balls) = (50C5)/(100C5) = 0.02814 to 5 decimal places.

Tina wants to install a square hot tub in her backyard.The backyard is 10feet by 50 feet ,and the hot tub will be 8 feet of the
Anestetic [448]

Answer:

436 square feet will not be provided for

Step-by-step explanation:

In this question, what we are simply asked to do is to calculate the area of the backyard that would be left after installing a square Hottub.

To get the answer here, what is necessary to do is to subtract the area of the square hot tub from the area of the rectangular yard.

Mathematically, the area of the mathematical yard would be :length * width: the length here is 10 feet and the width is 50 feet.

The area is thus 10 * 50 = 500 square feet

Now, we calculate the area of the square hottub = S^2 where S is the length of the side of the square. In this particular case, S = 8. The area of the square is thus; 8 * 8 = 64 square feet

Now the area left uncovered would now be; 500 sq feet - 64 square feet = 436 square feet

There are 10 sweets in a bag.
Valentin [98]

Answer:

See Explanation Below

Step-by-step explanation:

Given

Total Sweets = 10

Red = 4

Green = 2

Yellow = 3

Purple = 1

Required

a & b

The question is not properly presented; however the solution is as follows;

A.

Let P(Yellow) represent the probability of selecting a yellow sweet and n(Yellow) represent the number of Yellow sweets;

P(Yellow) = \frac{n(Yellow)}{Total}

P(Yellow) = \frac{4}{10}

P(Yellow) = 0.4

So, whichever letter that shows 0.4 or \frac{4}{10} is the probability of choosing a yellow sweet

B.

Let P(Orange) represent the probability of selecting an orange sweet and n(Orange) represent the number of orange sweets;

Since, there's no orange sweet in the bag;

n(Orange) = 0

P(Orange) = \frac{n(Orange)}{Total}

P(Orange) = \frac{0}{10}

P(Orange) = 0

In probability; opposite probabilities add up to 1;

Let P(Not\ Orange) represent the probability of choosing a sweet that is not orange

P(Not\ Orange)  + P(Orange) = 1

Substitute P(Orange) = 0

P(Not\ Orange)  + 0 = 1

P(Not\ Orange) = 1

So, whichever letter that shows 0 is the probability of choosing a sweet that is not orange

Lin has a marble that 5/8 inch wide. write the marbles width as a decimal. SHOW YOUR WORK
a_sh-v [17]
5/8 as a decimal would be 5/8 times 100/x because if you found the equivilent fraction you would be able to multiply it by the upside-down-fraction and get 1 for example 2/4 =1/2 if you multiply 4/2 with 1/2 you would get 4/4 or 1
so 5/8 times 100/x =500/8x=1
then use long division to solve 62.5/100=62.5%
