Example 3 If you roll a standard 6-sided die, what is the theoretical probability of getting a 4? Now, P(getting a 4) = (š‘µš’–š’Žš’ƒš’†š’“ š’š’‡ š’š’–š’•š’„š’š’Žš’†š’” š’˜š’‰š’†š’“š’† š’˜š’† š’„š’‚š’ š’ˆš’†š’• šŸ’)/(š‘»š’š’•š’‚š’ š’š’–š’Žš’ƒš’†š’“ š’š’‡ š’š’–š’•š’„š’š’Žš’†š’”) Total outcomes are 1, 2, 3, 4, 5, 6 āˆ“ Total number of outcomes = 6 And, Number of outcomes where can get 4 = 1 Thus, P(getting a 4) = (š‘š‘¢š‘šš‘š‘’š‘Ÿ š‘œš‘“ š‘œš‘¢š‘”š‘š‘œš‘šš‘’š‘  š‘¤ā„Žš‘’š‘Ÿš‘’ š‘¤š‘’ š‘š‘Žš‘› š‘”š‘’š‘” 4)/(š‘‡š‘œš‘”š‘Žš‘™ š‘›š‘¢š‘šš‘š‘’š‘Ÿ š‘œš‘“ š‘œš‘¢š‘”š‘š‘œš‘šš‘’š‘ ) = šŸ/šŸ”
