If the bird were just guessing there would be two options (right or wrong) and we would expect them to be equally likely to occur (50% chance for each). A 50% of correct, out of 12 cards gives us:
12×0.50=6
If the bird was guessing we would expect 6 correct answers. (1/2 of the total correct and 1/2 wrong.)
So the answer would be 6.

Step-by-step explanation:
The solution region is above the line with positive slope, and below the line with negative slope. It will be in the left quadrant of the X made by the crossing lines. The line with positive slope is steeper.
Answer:
MZA = 140
Step-by-step explanation:
5x+25°+ x + 17°=180°(Supplimentary Angles)
6x + 42° =180°
6x =180 - 42
6x=138
(divide by 6 both sides)
X= 23
substitution X into the given angle
5x +25
5(23)+25
115+25
140
