Algebra.Com's Answer #160223 by Theo(13342)![]() ![]() You can put this solution on YOUR website! numbers are 2 through 15. \n" ); document.write( "whole numbers. \n" ); document.write( "inclusive. \n" ); document.write( "p(<5) or > 10 \n" ); document.write( "----- \n" ); document.write( "you have number 2,3,4, and you have numbers 11,12,13,14,15 that you want the probability of drawing. \n" ); document.write( "the total set is 14 number from 2 through 15. \n" ); document.write( "----- \n" ); document.write( "you have one draw from the pot. \n" ); document.write( "----- \n" ); document.write( "the probability of getting a 2 or 3 or 4 is 3 out of 14. \n" ); document.write( "the probability of getting an 11 or 12 or 13 or 14 or 15 is 5 out of 14. \n" ); document.write( "----- \n" ); document.write( "the probability of getting A or B is the probability of getting A plus the probability of getting B. \n" ); document.write( "----- \n" ); document.write( "This equals 3 out of 14 plus 5 our of 14 = 8 out of 14. \n" ); document.write( "----- \n" ); document.write( "8 out of 14 can be reduced to 4 out of 7. \n" ); document.write( "----- \n" ); document.write( "The probability is 4/7 = .571428571 rounded to 57%. \n" ); document.write( " \n" ); document.write( " |
