Parts of a Circle
This is half of the diameter.
Radius
This is a solid whose six faces are all squares.
Cube
This describes the probability that you are in math class right now.
Certain (100%)
A coin is flipped 30 times and a Heads comes up 18 times. This is the experimental probability of flipping a Heads.
18/30 or equivalent (i.e. 3/5)
This is the name of a shape with 5 sides.
Pentagon
This is what the middle of the circle is called.
Center
This is a solid with 6 faces. Two faces are squares and four faces are rectangles.
Cuboid or Rectangular Prism
This describes the probability that Mr. Sullivan can fly like Superman.
Impossible (0%)
A coin is flipped 40 times and a Tails comes up 23 times. This is the experimental probability of flipping a Heads.
17/40
This is the name of a shape with 8 sides.
Octagon
This is the length of the perimeter (outside) of the circle.
Circumference
This is a solid with two circular bases and is in the shape of a can (e.g. soup can)
Cylinder
A fair coin is flipped (with sides Heads and Tails). This is the probability of flipping a Tails.
50% (0.5, even chance)
In a school survey of 100 students, 34 were in grade 9, 52 were were in grade 10, and 14 were in grade 11.
This is the experimental probability of a student being in grade 10.
52/100 (26/50 or 13/25)
An equilaterial triangle has this many lines of symmetry.
This is a line that connects two parts of the circle, but is NOT the diameter.
Chord
This is a solid that is in the shape of a ball.
Sphere
A fair six-sided die is rolled. This is the probability of rolling a 4.
1/6
In a school survey of 100 students, 25 were in grade 9, 37 were were in grade 10, and the rest were in grade 11.
This is the experimental probability of a student being in grade 11.
38/100 (14/50 or 7/25)
A shape whose sides are all equal and whose interior angles are all equal is called this.
Regular
This is a line that is outside of the circle, but touches the circle once.
Tangent
This is a solid with one base whose triangular faces meet at a point called the apex.
Pyramid
A fair six-sided die is rolled. This is the probability of rolling a number larger than 2.
2/3 (or 4/6)
A fair six-sided die is rolled 100 times. It was found that the experimental probability of rolling a 4 was 6/25.
This is how many times a 4 was rolled.
24 times
A rhombus has this order of rotational symmetry.
