Algebra.Com's Answer #785179 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "It appears you are misunderstanding the given data.... \n" ); document.write( "A regular die was rolled multiple times. It came up 1 6 times, 2 4 times, 3 1 time, 4 5 times, 5 2 times, and 6 an unknown number of times. \n" ); document.write( "None of the three questions can be answered with the given information. We either need to know the number of times a 6 came up, or we need to know the total number of times the die was rolled, so that we can determine the number of times a 6 came up. \n" ); document.write( "1. If your answer of 3 is correct, then the total number of rolls was 6+4+1+5+2+3 = 21. Was that total number of rolls given, and you forgot to include that information in your post? \n" ); document.write( "For 2 and 3, the experimental probability is the number of times a certain number came up, divided by the total number of rolls. \n" ); document.write( "Assuming the total number of rolls was in fact 21... \n" ); document.write( "2. P(2) = 4/21 \n" ); document.write( "3. P(4) = 5/21 \n" ); document.write( "---------------------------------------------------- \n" ); document.write( "The reader responded saying that the die was rolled 25 times. \n" ); document.write( "So, since the number of rolls other than 6 is 18, the answer to question 1 is that a 6 was rolled 7 times. \n" ); document.write( "And then the answers to questions 2 and 3 are 4/25 and 5/25 = 1/5. \n" ); document.write( " \n" ); document.write( " |
