a. Find the
b. Find the probability that 170 or more favor a charter school for grades K through 5.
c. Find the probability that no more than 1.0 favor a charter school for grades K through 5.
d. Find the probability that there are fewer than 130 that favor a charter school for grades K through 5.
e. Find the probability that exactly 150 favor a charter school for grades K through 5.
