2. what is the external probability of rolling a 4 3 what is the external probability of getting at least one tail

2. 1- Experimental probability of rolling a 4 = 40%

3. 2- Theoretical probability is 3%  greater than experimental probability.

Step-by-step explanation:

Experimental probability of rolling a 4 = 100 ×

                                                                  = 100 × 0.4

                                                                  = 40%

Experimental probability of getting at least one tail  =

                                                                                    = 0.72

Theoretical probability of getting at least one tail  =

                                                                                  = 0.75

Theoretical probability is 3%  greater than experimental probability.

the answer is 8/21

hope this
