A 60
C
15
1 8 30
D
10

We can expect 15 times an odd number when cube is rolled 30 times .

Step-by-step explanation:

Moises is rolling a number cube, with sides  numbered 1 through 6, 30 times. We need to find How many  times should he expect to roll an odd number . Let's find out:

We know that , in a cube numbered from 1 to 6 have 3 odd number as : 1,3,5

So , probability for an odd number is :

⇒

⇒

So , Number of we should expect for an odd number when cube is rolled 30 times is :

⇒

⇒

Hence , We can expect 15 times an odd number when cube is rolled 30 times .
