What is the probability of dying today?
This answer is based on current world estimates, and is therefore meaningless for any individual. There are about 7 billion 46 million people living, and about 150,000 people die per day according to one estimate. So the probability of dying today without any other qualifying information given is 150,000/7,046,000,000. This comes to about .0000213, and that is a very low probability indeed. In other words, .00213 percent of the world population is chosen by the grim reaper each day. If you assume the choice is random, then people in general don't have to worry much day by day.
Factors that would help us arrive at a better estimate for an individual are things like country of birth and country where currently living, age, occupation, many different general health questions including substance habits, diet, and activity, family history, and many others.
What is the probability of drawing two black sevens in succession?
The probability of drawing one black seven from a standard deck of cards is 2/52 = 1/26. The probability of drawing the other black seven from the remaining 51 cards is 1/51. Therefore the probability of drawing both black sevens from a deck of cards = 1/26 x 1/51 = 1/1326 ~ 0.000754 (3sf).

Why do we have to compute for the mean median mode and standard deviation?
To obtain a much better, simpler, and more practical understanding of the data distribution.
Can two mutually exclusive events occur at the same time?
No because the term mutually exclusive implies the the trials that could result in these events are sequenced in time.
