A probability model includes P(red) = 27 and P(blue) = 314. Which of the following probabilities could complete the model? Select all that apply. A. P(green) = 27, P(yellow) = 27 B. P(green) = 38, P(yellow) = 18 C. P(green) = 14, P(yellow) = 14 D. P(green) = 521, P(yellow) = 1121 E. P(green) = 37, P(yellow) = 114

Simplify 5 square root of 7 end root plus 12 square root of 6 end root minus 10 square root of 7 end root minus 5 square root of 6 . (1 point) 5 square root of 14 end root minus 7 square root of 12 5 square root of 7 end root minus 7 square root of 6 7 square root of 12 end root minus 5 square root of 14 7 square root of 6 end root minus 5 square root of 7

Sorry guys but as you have a small brain

What is the missing step in this proof ?
