Four rats are selected at random from a cage of 5 male (M) and 6 female (F) rats. If the random variable Y is concerned with the number of female rats taken out of the cage, construct the probability distribution and answer the questions below. (input up to 4 decimal places)A What is the probability that all selected rats are female? What is the probability that only one of the selected rats is female?
c. What is the probability that at least two of the selected rats is female?
What is the mean of the probability distribution?
E. What is the standard deviation of the probability distribution?

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
