Answer» Given : a simultaneous throw of a pair of dice To find : the probability of getting Solution: a pair of dice thrown total outcomes = 36 7 as sum ( 1 , 6) , ( 2, 5) , ( 3 ,4 ) , ( 4 , 3) , ( 5 , 2) , ( 6 , 1) Probability of 7 as sum = 6/36 = 1/6 a DOUBLET of odd number ( 1, 1) , ( 3, 3) , ( 5 , 5) probability of doublet of odd number = 3/36 = 1/12 not a doublet doublet = ( 1, 1) , ( 2, 2) , ( 3, 3) , ( 4, 4) , ( 5, 5) , ( 6, 6) Probability of not a doublet = 1 - 6/36 = 5/6 an odd number on the first dice Probability = 3/6 = 1/2 Learn more: if two dice are tossed, find the probability of throwing a total of 10 or ... a pair of dice thrown. find the probability of getting a sum of 10 or ...
