At a carnival, you spin a spinner that has four equal-sized sections, each a different color: green, yellow, red, and blue. if you land on green, you win 2 points. if you land on yellow, red, or blue, you lose 1 point. write the expected value equation. e (v) = startfraction 1 over a endfraction (2) startfraction 1 over b endfraction (c) startfraction 1 over d endfraction (e) startfraction 1 over f endfraction (g)

Answer 1

a = 4

b = 4

c = -1

d = 4

e = -1

f = 4

g = -1

Explanation:

that should be right
