Greater than 4 means either 5 OR 6, that means the probability of getting 5 or 6 is 2/6 ==>1/3

Theoretically she needs 3 Rolls to get a number greater than 4

Answer:

20 times

Step-by-step explanation:

We are given a cube that has s 6 faces that are numbered from 1 through 6.

She  expect to roll a number that is greater than 4 .

A number greater than 4 of dice = 5 or 6

Probability of getting 5  = \frac{\text{favorable event}}{\text{total events}}

Favorable event ={5}=1

Total events ={1,2,3,4,5,6}=6

So probability of getting 5  = \frac{1}{6}

Probability of getting 6  = \frac{\text{favorable event}}{\text{total events}}

Favorable event ={6}=1

Total events ={1,2,3,4,5,6}=6

So probability of getting 6  = \frac{1}{6}

Thus the probability of getting 5 or 6 = \frac{1}{6}+\frac{1}{6}

                                                              = \frac{2}{6}

                                                               = \frac{1}{3}

Since  She plans on rolling the number cube 60 times

So,she expect to roll a number that is greater than 4=  60*\frac{1}{3}

                                                                                             =20

Hence she should expect 20 times to roll a number that is greater than 4

In geometry, how do defined terms and undefined terms relate to each other

There are three words in geometry that are not formally defined. These three undefined terms are point, line and plane. 

POINT (an undefined term) 
In geometry, a point has no dimension (actual size). Even though we represent a point with a dot, the point has no length, width, or thickness. A point is usually named with a capital letter. In the coordinate plane, a point is named by an ordered pair, (x,y). 

LINE (an undefined term) 
In geometry, a line has no thickness but its length extends in one dimension and goes on forever in both directions. A line is depicted to be a straight line with two arrowheads indicating that the line extends without end in two directions. A line is named by a single lowercase written letter or by two points on the line with an arrow drawn above them. 

PLANE (an undefined term) 
In geometry, a plane has no thickness but extends indefinitely in all directions. Planes are usually represented by a shape that looks like a tabletop or wall. Even though the diagram of a plane has edges, you must remember that the plane has no boundaries. A plane is named by a single letter (plane m) or by three non-collinear points (plane ABC). 

Undefined terms can be combined to define other terms. Noncollinear points, for example, are points that do not lie on the same line. A line segment is the portion of a line that includes two particular points and all points that lie between them, while a ray is the portion of a line that includes a particular point, called the end point, and all points extending infinitely to one side of the end point. 

Defined terms can be combined with each other and with undefined terms to define still more terms. An angle, for example, is a combination of two different rays or line segments that share a single end point. Similarly, a triangle is composed of three noncollinear points and the line segments that lie between them. 

Everything else builds on these and adds more information to this base. Those added things include all the theorems and other "defined" terms like parallelogram or acute angle. <span>
