A six-sided number cube numbered 1 through 6 is rolled 2 times. What is the probability of getting an even number on both rolls?

1/4 OR 0.25

Step-by-step explanation:

The probability for rolling any even number on that six sided cube is 1/2. (2, 4, 6).

Therefore,

(Probabilty of choosing an even number) • (Probabilty of choosing an even number) = (Probabilty of choosing an even number twice)  

1/2 • 1/2 = 1/4

This can also be proven by doing a probability table wich takes 10 times longer than this quick equation. Any problems you have that follow this wording should be solved by using an equation like the one above.

NOTE: If the problem stated “what is the probability of getting an even number the first roll and a different even number on the second roll?” this would be solved as so:

1/2 • 1/3 = 1/6

This is because after one even number is chosen, the probabilty of choosing an even number drops by 1/6, which causes the probability for choosing any even number to change to 1/3.

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
