3. Bir rolls a standard six-sided die. Find the probability that a) He rolls a live b) He rolls a six c) He rolls a five and a six, simultaneously. ter d) He rolls a five or a six. c) The addition rule would have us believe that d - a + b-c. Is it true, in this case? "Doll a 5" and "rol! a 6" are examples of what linde of evente? Hint: te worde, starte with m. #4....
