Catherine has a number cube that has 6 faces that are numbered from 1 through 6. she plans on rolling the number cube 60 times. about how many times should she expect to roll a number that is greater than 4?

20 times

Step-by-step explanation:

We are given a cube that has s 6 faces that are numbered from 1 through 6.

She  expect to roll a number that is greater than 4 .

A number greater than 4 of dice = 5 or 6

Probability of getting 5  =

Favorable event ={5}=1

Total events ={1,2,3,4,5,6}=6

So probability of getting 5  =

Probability of getting 6  =

Favorable event ={6}=1

Total events ={1,2,3,4,5,6}=6

So probability of getting 6  =

Thus the probability of getting 5 or 6 =

                                                              =

                                                               =

Since  She plans on rolling the number cube 60 times

So,she expect to roll a number that is greater than 4=  

                                                                                             =20

Hence she should expect 20 times to roll a number that is greater than 4
