Exercise Name: | Multiplying dependent probabilities |
Math Missions: | High school statistics and probability Math Mission |
Types of Problems: | 3 |
The Multiplying dependent probabilities exercise appears under the High school statistics and probability Math Mission. This exercise practices formulas for multiplication and conditional probabilities.
Types of Problems[]
There are three types of problems in this exercise:
- Select what is true: This problem describes a situation and asks the student to select the answers from a list that are true statements.
- Use diagram and find probabilities: This problem has a diagram or chart drawn and asks the student to answer a sequence of questions about probability related to the situation.
- Use formulas: This problem asks the student to find a particular probability based on the formulas for conditional and conjunctive probabilities.
Strategies[]
This exercise is medium to get accuracy badges because there are a lot ways students can guarantee one true statement giving others. The speed badges are hard because the problems sometimes require a lot of thought to get correct.
- A useful formula that comes up is .
- If students get that then they know that the events are independent and vice versa.
- It is always true that
Real-life Applications[]
- Probability, along with decimals, percents, and fractions are used to determine the probability of a basketball player making a shot.
- Data and statistics appear in news reports and in the media every day.
- Many of the problems in this exercise could be viewed as real-life applications.
- Statistics can be seen more frequently than calculus in every day life.
