37. PROBABILITY The chance that the event will happen.

38. Will it rain? Do I need to carry an umbrella today?

39. - The probability based on reasoning, knowledge must be used in a certain situation to calculate the probability of an event that will happen. This is the probability based on math theory. Theoretical -what we expect to happen, the ratio of the number of favorable outcomes to the total number of outcomes.

40. Theoretical P (E) = Number of favorable outcomes Total number of outcomes

41. Without the data, what is the chance that it will rain today?

42. Clariss is asked to choose a day from a week. What is the probability of choosing a day which starts with S ?

43. If one letter is chosen from the capital of the country Indonesia, what is the probability that the letter chosen is a consonant?

52. It is all around us and we often come across real-life situations when we have to decide on making a choice from the available options. All these situation demand a decision from us and this is the time when probability theory comes to our rescue. You will come across instances when you have to face problems with respect to the outcomes of your decisions.

53. ACTIVITY
