Answer:

Step-by-step explanation:
We can form a right triangle and use trigonometry for a right triangle to solve this. The ground distance the plane travels is its displacement in the x-direction. The 2500 meters the plane moves through represents the hypotenuse of right triangle, and the ground distance is the adjacent leg of the
angle. Therefore, we set up the following equation:
, where
is the ground distance.
Solving, we get
.

Answer:
The probability of having exactly two girls is 3/8 or 0.375
Step-by-step explanation:
Since the likelihood is equal, the probability of having a boy = probability of having a girl = 1/2
In written form;
P(g) = P(b) = 1/2
We use the Bernoulli approximation to know the probability of having two girls.
Mathematically, that would be;
3C2 P(g)^2 P(b)^1
Inserting the values , we have;
3 * (1/2)^2 * (1/2)
= 3 * (1/2)^3 = 3/8 = 0.375
