a)
P(student makes more than 19 mistakes) = 1 - P(making less than 6 mistakes) - P(making 6 to 19 mistakes)
= 1-0.22-0.44 = 0.34
b)
P(student makes 6 or more mistakes) = P(making 6 to 19 mistakes) + P(making more than 19 mistakes)
= 0.44+0.34 = 0.78
c)
P(making 19 mistakes) = P(making at most 6 mistakes) + P(making 6 to 19 mistakes)
= 0.22+0.44 = 0.66
