Answer: 0.3125.
Step-by-step explanation:
- The chance of having a boy is 0.5, 
- the chance of having a girl is also 0.5.
<u>Outcome 1: all boys</u>
boy  boy  boy  boy
0.5 * 0.5 * 0.5 * 0.5 = 0.0625
<u>Outcome 2: first child is a girl, all others are boys</u>
girl   boy   boy   boy
0.5 * 0.5 * 0.5 * 0.5 = 0.0625
<u>Outcome 3: second child is a girl, all others are boys</u>
boy   girl   boy   boy
0.5 * 0.5 * 0.5 * 0.5 = 0.0625
<u>Outcome 4: third child is a girl, all others are boys</u>
boy   boy   girl   boy
0.5 * 0.5 * 0.5 * 0.5 = 0.0625
<u>Outcome 5: fourth child is a girl, all others are boys</u>
boy   boy   boy   girl
0.5 * 0.5 * 0.5 * 0.5 = 0.0625
Therefore,
0.0625 + 0.0625 + 0.0625 + 0.0625 + 0.0625 = 0.0625 * 5 = 0.3125
 
        
             
        
        
        
All are equal except A/D = C/B
I replaced the values with numbers
a=5 b=10 c=50 d=100
10/5=100/50 so it’s not b/a = d/c
5/10=50/100 so it’s not a/b = c/d
5/50 = 10/100 so it’s not a/c = b/d
5/100 is NOT 50/10 so it’s NOT a/d = c/b
        
             
        
        
        
Answer:
280 degrees
Step-by-step explanation:
To change radians to degrees, we can use the conversion factor
180/pi
14 pi/9  * 180/pi
Canceling like terms
14/9 * 180
280 degrees
