Use the given formula to calculate the probability

probability = number of desired outcomes
total number of outcomes

you are rolling a 6-sided number cube with the numbers 1 through 6. which of the following represents the probability of rolling an even number?

0
1/6
1/2
1

1/2

Step-by-step explanation:

There are six sides right? That be six numbers...

1 = odd

2 = even

3 = odd

4 = even

5 = odd

6 = even

There are a total of three odds, and three evens. Three is half of six so there is your answer!

step-by-step explanation:

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
