Since Jason rolls a cube labeled 1 through 6. Then to get any number when he rolls the cube probability will be = 1/6 = One event/ Total number of events
so probability of rolling a 3 = 1/6
Now he flips a coin then probability of getting head will be = 1/2
Since these two events are totally different therefore getting both the events ( getting 3 on rolling cube and flipping for head) will be = P1 × P2
There is no meaningful difference between the two mean monthly temperatures. Since the two MADs are 15 degrees and 13.7 degrees, there is no meaningful difference.
