Answer from: queen6931

1/36 ≈ 0.028

Step-by-step explanation:

In order to get a total of 2 if you roll 2 dice, you have to roll two ones. (You can't roll a 0 and 2 because an average die does not have a zero on it)

You have a 1/6 chance to roll a 1 on the first die; and you have a 1/6 chance to roll a one on the second die.

To find the probability of this happening together you have to multiply them together.

1/6 * 1/6 = 1/36 = 0.0277778 ≈ 0.028

22.22% probability of getting a total that is a factor of 6

Step-by-step explanation:

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

In this problem, we have these possible outcomes:

Format(Dice A, Dice B)

(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)

There are 36 possible outcomes.

Cases in which the total are factor of 6:

The factors of 6 are the number for which 6 is divisible by, so 1,2,3 and 6.

The cases that have these totals are:

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

8 outcomes, out of 36

8/36 = 0.2222

22.22% probability of getting a total that is a factor of 6

Answer from: lafuiciosa10

35/36

Step-by-step explanation:

total less than or equal to 2:

1+1

one option out of 6*6= 36

Probability of getting a total of 2: 1/6*1/6= 1/36

Probability of getting a total more than 2: 1-1/36= 35/36

Answer from: gabby0148

35/36

There are total of 36 outcomes.

Answer from: lovedavis9544

answer:

here is ur answer

Step-by-step explanation:

drawn 2 dice,

no of dice are= 1,1,2,2,3,3,4,4,5,5,6,6

total no are = 12

P (probability of getting more that 6) = 0/12

= 0 ans.

hope it will help you,plz mark me as branliest

Answer from: 203888

Number of possible outcomes of rolling 2 fair dice=36

Factors of 21=3,7

Possible outcomes of getting a total that is a factor of 21 is

1-2 ,

1-6,

2-1,

2-5,

3-4,

4-3,

5-2,

6-1

Number of possible outcomes of getting a total that is a factor of 21=8

probability of getting a total that is a factor of 21=8/36=2/9

Answer from: ebookhardt917

Step-by-step explanation:

Multiples of 5 = 5 and 10

Ways to roll a 5 = (1,4) ( 4,1) (2,3) (3,2)

Ways to roll a 10 = (5,5) (4,6) (6,4)

We have 7 possible outcomes for a multiple of 5...and there are 36 possible outcomes in total

So P (multiple of 5) = 7 / 36

Answer from: BluHope19

Step-by-step explanation:

No of possible outcome = 36

Factors of 21 = 3, 7

1 and 2

1 and 6

2 and 1

2 and 5

3 and 4

4 and 3

5 and 2

6 and 1

Number of possible outcomes of getting a total that is factor of 21 = 8

Probability = 2/ 9

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).

Hree experiments investigating the relation between need for cognitive closure and persuasion were performed. part of the study involved administering a "need for closure scale" to a group of students enrolled in an introductory psychology course. the "need for closure scale" has scores ranging from 101 to 201. for the 82 students in the highest quartile of the distribution, the mean score was x = 178.70. assume a population standard deviation of σ = 7.97. these students were all classified as high on their need for closure. assume that the 82 students represent a random sample of all students who are classified as high on their need for closure. find a 95% confidence interval for the population mean score μ on the "need for closure scale" for all students with a high need for closure. (round your answers to two decimal places.)
