document.write( "Question 1033625: Lauren is the point guard on her basketball team. She estimates that her chances of getting a 3-pointer are 85% when there is no one defending against her, but only 60% when there is a defender. There is a 50% chance that the girl assigned to defend her will not be close enough to block the shot. What is the probability of Lauren scoring a 3-point shot? \n" ); document.write( "

the way i see this problem is as follows:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "she has 85% probability to score the 3 pointer if the defender is not close enough to give her a hard time.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "she has 60% probability to score the 3 pointer if the defender is close enough to give her a hard time.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the defender has 50% probability to be close enough to give her a hard time.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the probability that she will make the shot is therefore .5 * .85 + .5 * .60 = .725.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "she will be able to score the 3 pointer 72.5% of the time overall.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "for example:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "assume she tries 1000 times.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "500 of those times the defender is close enough.
\n" ); document.write( "500 of those times the defender is not close enough.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "for the 500 of the times that the defender is close enough, she scores .60 * 500 = 300 times.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "for the 500 of the times that the defender is not close enough, she scores .85 * 500 = 425 times.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "for the 1000 times that she tries, she scores 300 + 425 = 725 times.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "725 / 1000 = .725 which is the probability we originally calculated above.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
