A school knows that 10% of its students are left-handed. What is the probability that there will be between 33 and 45 left-handed students in a
randomly selected group of 400? Use your calculator and this formula: P(a<
X < b) = binomcdf(n, p,b) - binomcdf(n, p,a - 1). Round your answer to three
decimal places.
A. 0.718
