Suppose you have 8 dice in a bag. You draw a single die and roll it. Three dice are standard fair dice, numbered 1-6 Two dice ar
Viktor [21]

Answer:

The probability of drawing a 4 is \frac{47}{240}

Step-by-step explanation:

We will assume that each of the dices is equally likely to be drawn. So, let us consider this three events: A is the event that we draw a traditional die, B is the event that we draw a die that has two 4's on it and C is that we draw a ten sided die.

Since they are all mutually exclusive events, we have that P(A) + P(B) + P(C)=1. We will find this probability by simply counting the number of ways in which we get the specific event and divided by the total number of outcomes.

Note that since we have 8 dice, and 3 dice are fair standard dice, P(A) = 3/8.

On the same fashion, we get that P(B) = 2/8, P(C) = 3/8.

No, we will calculate the probability of getting a 4 to each type of die. Let D be the event that we get a 4. So, we will calculate the conditionals probabilities P(D|A), P(D|B), P(D|C). Recall that P(D|A) is the probability of getting a 4, given that we draw a standard fair die.

So, suppose we get a standard die. Since it is fair and standard, we have that  the probability of getting a four is 1/6. Thus P(D|A) = 1/6.

If we get a die that has two 4's, we have double the chance of getting a 4, so the probability is 2/6. Then P(D|B) = 2/6.

Now, consider the case we get a 10-sided die. In here, we will assume that all odd numbers are equally likely between them and that even numbers are equally likely between them. When we throw the die, we get a number between 1 and 10. Since all possible outcomes of throwing the die once are mutually exclusive, we must have that P(1)+P(2)+...+P(10)= 1. Let c be the probability assigned to an odd number and 2c be the probability assigned to an even number. Then we have that

c+ 2c+c+2c+c+2c+c+2c+c+2c = 5c+5*(2c) = 15c = 1

which implies that c= 1/15. Then, in this case the probability of getting a 4 is 2c, i.e 2/15. Then P(D|C) = 2/15.

We will use the following theorem (total probability theorem). Given a partition of the sample space A_1, \dots , A_n (partition means mutually exclusive events) and an event B, then

P(B) = \sum_{i=1}^{n} P(A_i)P(B|A_i)

In our case, we are asked to calculate P(D). Then, by this theorem

P(D) = P(A)\cdot P(D|A)+P(B) P(D|B) + P(C) P(D|C) = \frac{3}{8}\cdot \frac{1}{6}+\frac{2}{8}\cdot \frac{2}{6}+\frac{3}{8}\cdot \frac{2}{15}= \frac{47}{240}

You entered a contest through your local television station. There is one first prize of a new car! There are 5 second place pri
Grace [21]

Answer:

\frac{1}{400} or 0.0025 0r 0.25%

Step-by-step explanation:

There are three categories that will get a prize

1) First place = 1 person

2) Second place = 5 persons

3) Third place = 20 persons

A total of 26 people will get prizes.

However, we want to determine your chance to win one of the second place prizes

There are 5 prizes in second place

This means out of a total of 2000 people, you could be among the 5

i.e 5 out of 2000

This is \frac{5}{2000} = \frac{1}{400} = 0.0025

This means you have a chance of 1 out of 400

= 0.25%

NEED HELP NOW!!!!
Dovator [93]

Answer:

f(x) = -3x --->#6

f(x) = |x-1|+3 --->#5

f(x) = √(x+3) --->#3

1/2x² --->#1

f(x) = (x+1)²-3 --->#4

4|x|--->#2

Step-by-step explanation:

Recall for transformations:

  • Adding a number outside the function moves it up
  • Subtracting a number outside the function moves it down
  • Adding inside the function moves it to the left
  • Subtracting inside the function moves it to the right
  • Multiplying to the function by a number less than 1 compresses
  • Multiplying to a function by a number greater than 1 stretched it
  • Multiplying by a negative flips the graph

f(x) = -3x

This is multiplication by a number greater than 1 and a negative so this stretches and flip. This is #6, a reflection.

f(x) = |x-1|+3

Subtraction inside the function shifts it to the right 1 and addition outside shifts it up 3. This is #5.

f(x) = √(x+3)

Addition inside the function shifts it to the left 3. This is #3

1/2x²

Multiplication by 1/2 which is less than 1 compresses it. This is #1.

f(x) = (x+1)²-3

Addition inside the function shifts the function to the left once. This is #4.

4|x|

Multiplying by 4, a number greater than 1, stretches it. This is #2.

What is the solution to the system of equations graphed below? y = x + 2 y = 3x – 2 A. (0, 2) B. (2, 4) C. (4, 2) D. (0, –2)
love history [14]

Answer:

B. (2, 4)

Explanation:

<u>Given equations</u>:

a) y = x + 2

b) y = 3x – 2

Solve them simultaneously:

x + 2 = 3x – 2

x - 3x = -2 - 2

-2x = -4

x = 2

Then find y = x + 2 = 2 + 2 = 4

Solution: (x, y) = (2, 4)
