You are rolling a pair of dice what's is the probability of getting different numbers on both dice
padilas [110]

Answer:

Pr = 0.833

Step-by-step explanation:

Given

A roll of a pair of dice

Required

The probability of getting different numbers

First, list out the sample space;

We have:

S = \{(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6),(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6),

(3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6),(4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)

 (5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6), (6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)\}

The total is:

Total = 36

The outcomes of the different numbers are:

Different = \{(1, 2) (1, 3) (1, 4) (1, 5) (1, 6),(2, 1) (2, 3) (2, 4) (2, 5) (2, 6),

(3, 1) (3, 2)(3, 4) (3, 5) (3, 6),(4, 1) (4, 2) (4, 3) (4, 5) (4, 6)

(5, 1) (5, 2) (5, 3) (5, 4) (5, 6), (6, 1) (6, 2) (6, 3) (6, 4) (6, 5) \}

The total is:

Different = 30

So, the probability of having a different outcome is:

Pr = \frac{Different}{Total}

Pr = \frac{30}{36}

Pr = 0.833

Ten thousand programs are printed for the basketball game. Only one displays the winning number. What is the probability that yo
Nitella [24]
From total of 10000 programs only one is winning.  The probability that you will get the winning number can be calculated as the ratio between the numbers of desired events and the total numbers of events. There is only one winning number , so the ratio is : 1/10000. If you purchase two programs the probability is the sum of the two probabilities: 1/10000+1/10000=2/10000.

Which of the following points would fall on the line produced by the point-slope form equation y - 2 = 3/2(x + 4) when graphed?
Zielflug [23.3K]

Answer:

c. (-2, 5)

Step-by-step explanation:

y - 2 = 3/2(x + 4)

to know which is the correct option we have to replace the equation x and y with what is in the point

a.

y - 2 = 3/2(x + 4)

(-1) - 2 = 3/2((-2) + 4)

-3 = 3/2(2)

-3 = 3

Wrong

b.

y - 2 = 3/2(x + 4)

(5) - 2 = 3/2((-6) + 4)

3 = 3/2(-2)

3 = -3

Wrong

c.

y - 2 = 3/2(x + 4)

(5) - 2 = 3/2((-2) + 4)

3 = 3/2(2)

3 = 3

Correct

d.

y - 2 = 3/2(x + 4)

(-1) - 2 = 3/2((6) + 4)

-3 = 3/2(10)

-3 = 15

Wrong
