A six–faced die was rolled 250 times in an experiment. Consider the following events:
A: “getting a number greater than 6”
B: “getting a number from 1 to 6”
a. (i) Define (a) a certain event, and (b) an impossible event.
b. (ii) Event A did not occur in any of the 250 trials. Write the empirical probability P(A) and state the type of event A is.
c. (iii) Event B occurred in every one of the 250 trials. Write the empirical probability P(B) and state the type of event B is.
