A number cube with the numbers 1 through 6 is rolled. What is the probability of the number cube showing a 4 or a number less th
Sonja [21]

Answer:

Step-by-step explanation:

The probability is

P

(

A

)

=

1

3

Explanation:

To calculate the probability you have to count the number of all possible results

|

Ω

|

and the number of results that fulfill the given condition

|

A

|

.

In this case

Ω

=

{

1

,

2

,

3

,

4

,

5

,

6

}

Thereare 6 possible result of a dice toss. So

|

Ω

|

=

6

The given condition is "the result is divisible by

3

", so

A

=

{

3

,

6

}

- those are the only numbers divisible by

3

, so

|

A

|

=

2

.

Finally to calculate the probability we have to divide

|

A

|

by

|

Ω

|

.

P

(

A

)

=

|

A

|

|

Ω

|

=

2

6

=

1

3

Note The probability is never larger than

1

, so if you get such result then there must be a mistake in calculations.

2 3/6 boxes and 1 2/3 boxes were recycled what is the total
Liono4ka [1.6K]
Since you are recycling the boxes you will be subtracting 2 3/6 and 1 2/3 since you’re a denominators you’re not mad she have to find a common denominator which would be six. So you have to do 2/2 x 2/3 = 4/6. So then you would do 3/6 - 4/6 = 1/6. Then you would subtract 1-2=1. Then you would do 1 + 1/6 = 1 1/6

So the answer is 1 1/6.
I hope this helped

How much would a $3500 piano cost if it was on sale for 20% off with the 6% sales tax on the
Bess [88]

I'm not sure if you meant the tax was on the original proce or not, so here's both answers:

Tax on original price: $3010

Tax after sale: $2968

To get the amount off from the sale

3500x.2=700

3500-700=2800

To get the tax

(Tax on original price) 3500x.06=210

(Tax after sale) 2800x.06=168

Add tax onto price

(Tax on original price) 2800+210=3010

(Tax after sale) 2800+168=2968
