You roll a standard number cube. find p(3 or 4).

Step-by-step explanation:

Total number of events on dice = {1,2,3,4,5,6}=6

Favorable event = {3}=1

So, probability of getting 3 on dice =

                                                         =

Favorable event = {4}=1

So, probability of getting 4 on dice =

                                                         =

So, probability of getting 3 or 4 on a dice =  

                                                                     =  

                                                                     =  

Hence P(3 or 4) is
