The surface of a circular dart board has a small center circle called the bull's-eye and 20 pie-shaped regions numbered from 1 to 20. each of the pie-shaped regions is further divided into three parts such that a person throwing a dart that lands in a specific region scores that value of the number, double the number, or triple the number, depending on which of the three parts the dart hits.
if a person hits the bull's-eye with probability 0.01, hits a double with probability 0.15, hits a triple with probability 0.20, and misses the dart board with probability 0.64.what is the probability that 8 throws will result in:
a. no bull's eye
b.3 triples
c. a double twice
d.3 complete misses
