A stack of four cards contains two red cards and two black cards. I select two cards, one at a time, and do not replace the first card selected before selecting the second card. Consider the events:A = the first card selected is red. B = the second card selected is red. The events A and B are:conditionals. independent. disjoint. None of the answer options are correct.

(A)Conditionals

Step-by-step explanation:

The stack of four cards contains two red cards and two black cards.

Given the events

A = the first card selected is red.

B = the second card selected is red.

The two events A and B are conditionals because the probability of event B occurs given that event A has already occurred.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
