Anumber cube is rolled 300 times. predict how many times a number greater that 3 would be rolled

150

Step-by-step explanation:

4, 5 and 6 are all numbers greater than 3.

The chances of rolling a 4 is 1/6, that of a 5 is 1/6, and that of a 6 is 1/6.

The chances of rolling a number greater than 3 is thus 3/6, or 1/2.

This is theoretical probability; you haven't actually observed this happening.

We can now multiply (300 rolls) by this probability 1/2, obtaining 150.

We predict that in 300 rolls, 150 numbers greater than 3 would be rolled.

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
