The all possible eight outcomes of boy or girl birth when a couple have three children is
(GBB) , (GBG), (GGB) , (GGG), (BBG), (BGB), (BGG), (BBB)
Where B represents boy and G represents Girl
The probability that having exactly 1 girl is
= Number of outcomes with one girl / Total numbers of outcomes
Now Number of outcomes with only one girl = GBB, BGB, BBG = 3
So the probability will be
The probability that having exactly 1 girl is = 3/8 = 0.375
The probability that when a couple has three children, there is exactly 1 girl is 0.375
Answer:
FIGURE 1:
x = 118; y = 96
FIGURE 2:
x = 85; y = 65
Step-by-step explanation:
FIGURE 1:
You know that x = 118 because of the Corresponding Angles theorem.
Because of the Exterior Angle Theorem (triangles), you can then figure out what y is with the following equation: y + 22 = 118 to get y = 96.
FIGURE 2:
In this figure, you first need to determine what the third angle in the bottom right triangle is. Using the Triangle Sum Theorem, you would find that the third angle is 70.
Because of the Vertical Angles Theorem, you know that the third angle in the top left triangle is also 70. With this information, you can now solve for x using the Triangle Sum Theorem to get x = 85.
Now that you know x, you can solve for y. The other 3 angles in the quadrilateral in which y is a part of are 90, 110, and 95. These could be figured out using the Linear Pair Postulate, the Vertical Angles Theorem, and the Linear Pair Postulate respectively. Now you can figure out y by using the Quadrilateral Sum Conjecture to get y = 65.
Percent means parts out of 100
18%=18/100=1.8/10=0.18
0.18<0.70
18%<0.7
0.7 is larrger because math
