Best ResponseYou've already chosen the best response.0possible events for a sum of 11 or more than 11 are 56,65,66 no. of events=3 total no. of events=36 P(for a sum 11 or more )=3/36=1/12 P(for a sum less than 11)=11/12=?

Best ResponseYou've already chosen the best response.0The probability of an event happening is the number of ways the even can happen divided by the total number of ways. When you roll 2 dice, what is the total number of outcomes?

Best ResponseYou've already chosen the best response.0Below you see all possible outcomes of rolling 2 dice. How many outcomes are there? 11, 12, 13, 14, 15, 16 21, 22, 23, 24, 25, 26 31, 32, 33, 34, 35, 36 41, 42, 43, 44, 45, 46 51, 51, 53, 54, 55, 56 61, 62, 63, 64, 65, 66

Best ResponseYou've already chosen the best response.0One single die has 6 outcomes, but when you roll two dice, you need to find all possible combinations of outcomes of the two.

Best ResponseYou've already chosen the best response.0Look above. Each pair of numbers is a different outcome. There are 36 possible different outcomes.

Best ResponseYou've already chosen the best response.0When a pair of dice are rolled, there are 36 possible different outcomes. Now you need to find out how many of the 36 different outcomes have a sum less than 11.

Best ResponseYou've already chosen the best response.0You add the numbers of the two dice. All outcomes in black below are less than 11. The outcomes in red are 11 or more. \(11, 12, 13, 14, 15, 16 \) \(21, 22, 23, 24, 25, 26 \) \(31, 32, 33, 34, 35, 36 \) \(41, 42, 43, 44, 45, 46 \) \(51, 51, 53, 54, 55, \color{red}{56} \) \(61, 62, 63, 64, \color{red}{65}, \color{red}{66}\)

Best ResponseYou've already chosen the best response.0Out of 36 outcomes, only 3 are 11 or more. That means 33 are less than 11.

Best ResponseYou've already chosen the best response.0So the probability of getting a sum less than 11 when a pair of dice are rolled are 33/36?

mathstudent55

Best ResponseYou've already chosen the best response.0Now you see that your desired outcomes are 33,and the total outcomes are 36. The probability of rolling a number less than 11 is \(p(less~ than~ 11) = \dfrac{33}{36} \)

mathstudent55

Best ResponseYou've already chosen the best response.0Correct. Now you need to reduce 33/36.

Best ResponseYou've already chosen the best response.0\[1\frac{ 1 }{ 12 }=\frac{ 121 }{ 12 }=\frac{ 11 }{ 12 }\]
