You roll two six-sided fair dice. a. Let A be the event that the first die is even and the second is a 2, 3, 4 or 5

1/3

Step-by-step explanation:

In the event that he first roll is even is 1/2 the probability of the 2nd one being 2 3 4 or 5 is 2/3

We multiply them together to get 2/6 or 1/3

So the probability is 1/3

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.
