Hi \r \n" ); document.write( "\n" ); document.write( "There are 5 reds, 2 whites and 3 greens = 10 total\r \n" ); document.write( "\n" ); document.write( "Find the probability of randomly selecting\r \n" ); document.write( "\n" ); document.write( "a) a red ball - So there are 5 red and there are 10 in total so the probability of selecting a red ball is 0.5 or 50%\r \n" ); document.write( "\n" ); document.write( "b) a green ball - so there are 3 green and 10 in total so the probability of selecting a green ball is 0.3 or 30%\r \n" ); document.write( "\n" ); document.write( "c) a ball that is not red - so 10 - 5 (which is the total minus the number of red balls) = 5 green/white so the probability is 0.5 or 50%\r \n" ); document.write( "\n" ); document.write( "d) there are no black balls so it is impossible to select a black ball\r \n" ); document.write( "\n" ); document.write( "e) a white ball - 2 white balls so 20% or 0.2 chance\r \n" ); document.write( "\n" ); document.write( "Hope this helps \n" ); document.write( " |
