1. Let X be a binomial random variable with n = 20 and p = .3. A. Write the expression for P(x = 6) in terms of the formula
, then
evaluate it using your calculator. (1 point)
B. Using probability notation, P(X = x), write out all the probabilities you'd need to add
up in order to calculate P(X < 6), and then evaluate it using your calculator. (1 point)
C. For part B, why did you choose the upper bound that you did? If you were using the
normal approximation could you choose a different upper bound? Why or why not?

1. what is the formula for finding the vertical distance between two points on a coordinate plane?

Ming says that 0.24 > 1/4 because 0.24= 2/4. which best explains mings error

Write the contrapositive of the conditional statement. determine whether the contrapositive is true or false. if it is false, find a counterexample. a converse statement is formed by exchanging the hypothesis and conclusion of the conditional. a) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. true b) a statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. false; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional. c) a non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. false; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional. d) a statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. true
