Four 6-sided dice are rolled. The dice are fair, so each one has equal probability of producing a value in {1, 2, 3, 4, 5, 6}. Let X = the minimum of the four values
rolled. (It is fine if more than one of the dice has the minimal value.). What is
P (X ≥ k) as a function of k?

Without graphing the linear functions, find the coordinates of the point of intersection of their graphs: y=3x−11 and y=4

Hillel is juggling flaming torches to raise money for charity. his initial appearance raises $500\$500 $500 , and he raises $15\$15 $15 for each minute of juggling performance. the amount rr r of money hillel raises is a function of tt t , the length of his performance in minutes. write the function's formula.

Logan wants to know how many skateboards have defective parts. he inspects 20,000 skateboards and keeps track of the number of defects per board. use his probability distribution table to find the expected value for defects on a skateboard.
