What is the complement of a set W, denoted as W'?

Back

The complement of a set W, denoted as W', includes all elements not in W. For example, if the universal set is G and W = {1, 2, 3}, then W' = G - W.

How do you calculate the surface area of a sphere?

Back

The surface area (SA) of a sphere is calculated using the formula: SA = 4πr², where r is the radius of the sphere.

What is the union of two sets A and B, denoted as A ∪ B?

Back

The union of two sets A and B, denoted as A ∪ B, is the set of elements that are in A, in B, or in both. For example, if A = {1, 2, 3} and B = {2, 4, 6}, then A ∪ B = {1, 2, 3, 4, 6}.

What is the probability of an event?

Back

The probability of an event is a measure of the likelihood that the event will occur, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

How do you find the surface area of a cylinder?

Back

The surface area (SA) of a cylinder is calculated using the formula: SA = 2πr(h + r), where r is the radius and h is the height of the cylinder.

Front

What is a Venn diagram used for?

Back

A Venn diagram is a visual representation used to show the relationships between different sets, including their intersections and unions.

Front

What is the formula for the area of a triangle?

Back

The area (A) of a triangle is calculated using the formula: A = 1/2 * base * height.

Front

What is the difference between a permutation and a combination?

Back

A permutation is an arrangement of items where order matters, while a combination is a selection of items where order does not matter.

Front

How do you calculate the surface area of a rectangular prism?

Back

The surface area (SA) of a rectangular prism is calculated using the formula: SA = 2(lw + lh + wh), where l is length, w is width, and h is height.

Front

What is the formula for the circumference of a circle?

Back

The circumference (C) of a circle is calculated using the formula: C = 2πr, where r is the radius of the circle.
