quizlet "it is closed under addition and multiplication but not closed under subtraction or division."
deff fn [24]

Rational numbers are closed under addition ,multiplication but not closed under division

Rational number

Closure property

assume two rational numbers say x and y. the results  of addition and multiplication operations give a rational number we can say that rational number are closed under addition and multiplication . For example

rational number are not closed under division as  1 and 0 are rational number  but 1/0 is not defined but it is closed under addition  and multiplication

that is 1+0 = 1 closed under addition

          1*0 =0 closed under multiplication

but 1/0  is not defined so it is not closed under division

Hence Rational numbers are closed under addition ,multiplication but not closed under division

A fair four-sided spinner has the numbers 1 to 4 marked on its sides. It is spun twice and the two scores are added together.
scZoUnD [109]

Answer:

Probability of getting doubles = 1/4

Step-by-step explanation:

Given - A fair four-sided spinner has the numbers 1 to 4 marked on its sides. It is spun twice and the two scores are added together.

To find - Using a sample space diagram, find the probability of getting a double.

Proof -

Given that,

A four-sided spinner is spin twice.

So,

The Sample Space becomes

S = { (1, 1), (1, 2), (1, 3), (1, 4)

       (2, 1), (2, 2), (2, 3), (2, 4)

       (3, 1), (3, 2), (3, 3), (3, 4)

       (4, 1), (4, 2), (4, 3), (4, 4) }

So,

n(S) = 16

Now,

Let A is the event Getting a double, So,

A = { (1, 1), (2, 2), (3, 3), (4, 4) }

and

n(A) = 4

So,

The Probability of getting doubles = n(A) ÷ n(S)

                                                         = 4 ÷ 16

                                                         = 1/4

∴ we get

Probability of getting doubles = 1/4
