How many ways are there to assign 8 visiting different studetns to one Stony Brook summer course, chossing from Calculus I, Linear Algebra or Basketweaving, if each course must have at least one students from Iceland?

56 ways

Step-by-step explanation:

Number of ways is given by n combination r (n! / (n - r) ! r!)

n = total number of students = 8, r = the number of summer courses = 3

Number of ways = 8 combination 3 = 8! / (8-3) !3! = 8!/5!3! = 8*7*6*5!/5!*6 = 8*7 = 56 ways
