Mrs. Chauvet has an unfair number cube that lands with 6 facing up 40% of the time. Let X = the number of times that she rolls a 6 among 3 trials. Here is a binomial probability table for this setting. X 0 1 2 3 P(X) 1(0.6)3 3(0.4)(0.6)2 3(0.4)2(0.6) 1(0.4)3 Find each probability. Enter your answer to 3 decimal places. P(X < 1) = P(X ≤ 1) =

Use the following statements to write a compound statement for the conjunction or disjunction. then find its truth value. p: an isosceles triangle has two congruent sides. q: a right angle measures 90° r: four points are always coplanar. s: a decagon has 12 sides. a) a right angle measures 90° or an isosceles triangle has two congruent sides; true. b) a right angle measures 90° and an isosceles triangle has two congruent sides; true. c) a right angle measures 90° and an isosceles triangle does not have two congruent sides; false. d) a right angle measures 90° or an isosceles triangle does not have two congruent sides; true.
