begin mathsize 16px style Let space straight A subscript 1 space be space the space scooter space driver straight A subscript 2 space be space the space car space driver straight A subscript 3 space be space the space truck space driver. Total space number space of space drivers equals 2000 plus 4000 plus 6000 equals 12000 straight P open parentheses space straight A subscript 1 space close parentheses equals 2000 over 12000 equals 2 over 12 straight P open parentheses straight A subscript 2 close parentheses equals 4000 over 12000 equals 4 over 12 straight P open parentheses straight A subscript 3 close parentheses equals 6000 over 12000 equals 6 over 12 straight P open parentheses straight E divided by straight A subscript 1 close parentheses equals straight P open parentheses scooter space driver space met space with space an space accident close parentheses equals 0.01 straight P open parentheses straight E divided by straight A subscript 1 close parentheses equals straight P open parentheses car space driver space met space with space an space accident close parentheses equals 0.03 straight P open parentheses straight E divided by straight A subscript 3 close parentheses equals straight P open parentheses truck space driver space met space with space an space accident close parentheses equals 0.15 Using space Baye apostrophe straight s space theorem comma we space get fraction numerator begin display style 2 over 12 end style cross times 0.01 over denominator 1 over 12 cross times 0.01 plus 4 over 12 cross times 0.03 plus 6 over 12 cross times 0.15 end fraction equals 1 over 52 end style
