If a dice is rolled and a coin is tossed, answer the following questions: \n" ); document.write( "a. Provide the sample space of the above event \n" ); document.write( "6 pairs with \"head\" and 1,2,3,4,5,6 \n" ); document.write( "6 pairs with \"tail\" and 1,2,3,4,5,6 \n" ); document.write( "------------------------------------------------ \n" ); document.write( "b. What is the probability that the dice shows odd number and the coin shows head? \n" ); document.write( "(head,1);(head,3);(head,5) \n" ); document.write( "Ans:: 3/12 = 1/4 \n" ); document.write( "------------------------------ \n" ); document.write( "c. Now a coin is tossed only three times but it is biased to get 75% head. What is the probability of getting one head and two tails in any order? \n" ); document.write( "Patterns:: (h,t,t)(t,h,t)(t,t,h) \n" ); document.write( "P(h,t,t) = 1/4*(3/4)^2 = 9/48 \n" ); document.write( "P(t,h,t) = (1/4)(3/4)^2 = 9/48 \n" ); document.write( "P(t,t,h) = (1/4)(3/4)^2 = 9/48 \n" ); document.write( "----- \n" ); document.write( "Ans:: 27/48 \n" ); document.write( "--------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "--------------- \n" ); document.write( " |
