Sarah is playing a game that requires each player to spin an arrow to one of four colors, equally divided: red, yellow, blue, or green. Three players before Sarah spun the arrow to yellow, but Sarah really wants her arrow to land on red. How is the probability of Sarah’s spin affected by the spins of previous players? 1. Sarah’s spin is an independent event and is therefore not affected by previous spins. 2. The probability of Sara landing on red increases but only slightly because of previous spins. 3. The probability of Sarah landing on red decreases significantly because the other players landed on yellow. 4. Sarah has a much higher probability of landing on red because the previous players landed on yellow.

1. Sarah's spin is an independent event and is therefore not affected by previous spins.

Step-by-step explanation:

The the spins by the other players has no affect on Sarah's spin.

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
