Algebra.Com's Answer #759826 by greenestamps(13208) You can put this solution on YOUR website! \n" ); document.write( "I don't know what it is you need help with on this; the instructions seem straightforward, and the questions are simple.... \n" ); document.write( "a) The possible outcomes are all the 2-digit numbers with both digits between 1 and 6 (inclusive). There are 6*6=36 such numbers. You can make the table. \n" ); document.write( "b) As an example of these questions, the 2-digit prime numbers with both digits between 1 and 6 are 11, 13, 23, 31, 41, 43, 53, 61. That's 8 numbers; the probability that one of the outcomes randomly selected is prime is 8/36 = 2/9. \n" ); document.write( "You can work the other problems similarly. \n" ); document.write( " |
