Making Predictions With Probability Worksheet

4 problems

Probability is the likelihood of an event occurring. Mathematically, the ratio of the number of favorable outcomes to the total number of outcomes is probability. It has excellent applications in games, in business, and so on. The probability formula is the number of favorable Outcomes / Total Number of Possible Outcomes. 


 

There are some terms one should keep in mind while solving problems on probability.

Teaching Making Predictions with Probability Easily 

 

  • Experiment: An operation conducted to produce an outcome. 


 

  • Sample Space: The total possible outcomes in an experiment. 


 

  • Favorable Outcome: An event that has produced a desired result is the favorable outcome. 



 

Probability = Number of Favorable Outcomes / Total Number of Possible Outcomes

  • P(B) = probability of an event 'B'.
  • n(B) = number of favorable outcomes of an event 'B'.
  • n(S) = total number of events occurring in a space.
