Front

What is the formula to calculate speed?

Back

Speed = Distance / Time

Front

What is the probability of an event?

Back

Probability = Number of favorable outcomes / Total number of outcomes

Front

How do you calculate the probability of NOT landing on a specific outcome?

Back

Probability of NOT A = 1 - Probability of A

Front

What is the total probability of selecting a non-drama movie from a list of movie genres?

Back

Total Probability = (Total Movies - Number of Dramas) / Total Movies

Front

What is the sum of the angles in a triangle?

Back

The sum of all angles in any triangle is equal to 180°.

Front

In an isosceles triangle, if the base angles are equal, how do you find the missing angle?

Back

Use the equation: 2 * Base Angle + Missing Angle = 180°

Front

What is the expected value in probability?

Back

Expected Value = (Probability of Outcome 1 * Value of Outcome 1) + (Probability of Outcome 2 * Value of Outcome 2) + ...

Front

How do you find the expected number of times an event occurs in probability?

Back

Expected Number = Total Trials * Probability of the Event
