Answer:
We have a binomial probability distribution, in which:
P(X = 0) = 0.064
P(X = 1) = 0.288
P(X = 2) = 0.432
P(X = 3) = 0.216
Step-by-step explanation:
For each flight, there are only two possible outcomes. Either it is for domestic travel, or it is for international travel. Flights are independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Let x be the number of requests among the next three requests received that are for domestic flights.
3 flights, and 60% are for domestic travel. This means that . The probabilities are given by:

Step-by-step explanation:
A polygon in the plane has rotational symmetry if the figure can be mapped onto itself by rotating between 0 and 360° about it's center.
So, we need to find the number of symmetrical line a regular polygon can have.
Note : A regular polygon with n sides has n lines of symmetry and order of symmetry n.
Then, let n be number of symmetrical line lines
Then,
Smallest angle of rotation about the center for which the polygon will be mapped unto itself is
360 / n
FA = FD = 12/2 = 6
FC is given as 8. FA+FC = 14 is half the perimeter.
So the perimeter is 2(6+8) = 28 . . . . . . matches selection A
