If 90% of students are right handed, use the Poisson distribution to estimate the probability that a sample of 80 students has 5 or more right-handed students.
Please help with this problem!

Calculate the mean number of right-handed students in the sample. Then use the Poisson distribution with that mean to calculate the estimated probability.
