Algebra.Com's Answer #52147 by blfaust(5)![]() ![]() ![]() You can put this solution on YOUR website! 1. The probability of heads is one-half Also 3 and 5 are the only primes between 1 and 6 that are greater than 2. So, \n" ); document.write( "2. The word \"DIVISIBILITY\" contains 11 letters and it has five \"I's\" in it. So the chance of the first card having an \"I\" is 5/11. Now that one card with an \"I\" is gone, because P stated you were going to pull an \"I\" followed by another \"I\", you only have four \"I's\" left and ten cards total. 4/10 reduced is 2/5 Multiply them together to find the P of both of them happening. \n" ); document.write( "3. x+y=35 and x*y=300 Create a chart of numbers that add up to 35. Ex. 34+1...33+2...32+3...down to 18+17. You will see that there are only seventeen pairs of numbers to choose from. Now find a pair that gives you a product of 300. Soon you will see that 20*15+300. Since Sue is younger, Sam is 20. \n" ); document.write( " |
