What is the formula for calculating the probability of an event?

Back

The probability of an event is calculated using the formula: P(Event) = (Number of favorable outcomes) / (Total number of outcomes).

How do you find the median of a set of numbers?

Back

To find the median, arrange the numbers in ascending order and identify the middle number. If there is an even number of values, the median is the average of the two middle numbers.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = (Base × Height) / 2.

Front

If a recipe requires a ratio of flour to sugar, how do you determine the amount of flour needed for a given amount of sugar?

Back

Use the ratio to set up a proportion. For example, if the ratio is 2 cups of flour for every 3 cups of sugar, and you have 6 cups of sugar, you can set up the equation: (2/3) = (x/6) and solve for x.

Front

What is the formula for the surface area of a cube?

Back

The surface area of a cube is calculated using the formula: Surface Area = 6 × (side length)².

Front

What is the total number of marbles in a bag containing 3 red, 5 blue, and 2 green marbles?

Back

The total number of marbles is 3 + 5 + 2 = 10.

Front

How do you calculate the probability of drawing a specific color marble from a bag?

Back

To calculate the probability, divide the number of marbles of that color by the total number of marbles in the bag.

Front

What is the median of the following set of scores: 70, 85, 90, 95?

Back

The median is 87.5, which is the average of the two middle scores (85 and 90).

Front

What is the area of a triangle with a base of 10 cm and a height of 6 cm?

Back

The area is 30 cm², calculated as (10 cm × 6 cm) / 2.

Front

If a recipe requires 2 cups of flour for every 3 cups of sugar, how many cups of flour are needed for 6 cups of sugar?

Back

You need 4 cups of flour, calculated using the ratio 2:3.
