If the probability that alex lives to be 100 years old is 0.06%, what is the
probability that alex does not live to be 100 years old?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

Xis -1/2
y is 35/4.
