What is the probability of these events when we randomly select a permutation of {1, 2, 3, 4}? 1. a) 1 precedes 4.
2. b) 4 precedes 1.
3. c) 4 precedes 1 and 4 precedes 2.
4. d) 4 precedes 1, 4 precedes 2, and 4 precedes 3.
5. e) 4 precedes 3 and 2 precedes 1.

i will pick c put check it over to be sure

step-by-step explanation:

x-3y=4

step-by-step e

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
