Compute these probabilities

a. The probability of rolling the number 6 using one die.

b. The probability of rolling the number 6 twice in 2 rolls using only one die.

c. If the probability of seeing a male house finch at a birdfeeder is .45 and the probability of seeing a female house finch is .35; what is the probability of seeing, first a male house finch, then a female house finch, and finally another male house finch?

d. There is only 2 type of Pokemon: rare and common.  If the probability of finding a rare Pokemon at a Pokestop is .05, what is the probability that the first 8 Pokemon that you find are common, and you find one rare Pokemon at a Pokestop that has a lure attached to it.  Assume that you will find at least 9 Pokemon in the 30 minutes that the lure is attached.
