The number of lightning strikes in a year at the top of a particular mountain has a poisson distribution with a mean of 3.8. fin
1 answer:
Let X be the number of lightning strikes in a year at the top of particular mountain.
X follows Poisson distribution with mean μ = 3.8
We have to find here the probability that in randomly selected year the number of lightning strikes is 0
The Poisson probability is given by,
P(X=k) =
Here we have X=0, mean =3.8
Hence probability that X=0 is given by
P(X=0) =
P(X=0) =
P(X=0) = 0.0224
The probability that in a randomly selected year, the number of lightning strikes is 0 is 0.0224

To answer this, we need to use the rules of geometric shapes. An equilateral triangle is equiangular, meaning all its angle measures are equal. Since all triangles' angles add up to 180°, simply divide 180 by three to find the angle measure of each angle:
Therefore, the measure of the triangle's angle is 60°
Next, we know that a characteristic of a rectangle is that each angle must be a right angle, or an angle with a measure of 90°.
Now, all we have to do is use the sum of all the angle measures to figure out the missing piece:
The missing angle measure, angle x, equals 18°.
Hope this helps!
