Answer:
99.86%
Step-by-step explanation:
What we have here is a binomial distribution, let x be the baby number among 8 births.
Binomial (n = 8, p = 0.559)
We want to find, P (X ≥ 1)
P (X ≥ 1) = 1 - P (X <1)
P (X ≥ 1) = 1 - P (X = 0)
P (X = 0) = 8C0 * (0.559) ^ 0 * (1 - 0.559) ^ (8-0)]
8C0 = 8! / (0! * (8-0)!) = 1
replacing we have:
P (X = 0) = 1 * 1 * 0.0014
P (X = 0) = 0.0014
P (X ≥ 1)) = 1 - 0.001
4
P (X ≥ 1) = 0.9986
Therefore the probability is 99.86%

The <em><u>correct answer</u></em> is:
HL
Explanation:
These will both be right triangles, as angle Q and angle Q' are both 90 degrees.
Since Q and Q' are the right angles, this means that RS and R'S' are the hypotenuses of the two right triangles.
Since Q'R'S' was created by translating QRS, a corresponding leg of both triangles will be congruent; this gives us hypotenuse-leg, or HL.
