The restaurants Andi and equal to 10 and are equal to flight and c are equal Do in factorial divided by n minus r factorial in tow Our factory now we will substitute the values off and on are and factorial is 10 factorial do it it by 10 minus five factorial in tow R factorial is five factorial 10 factorial is then in do nine into eight in tow, seven into six and two five Factorial, that is five. Factorial is firing to foreign toe trained to do into one but your 10 minus five East five factorial That's what we help but it doesn't like that into our factory is also five factorial. We can cancel five factorial in numerator and denominator. So then in don't nine into eight into seven in tow six in Duke six dueted by five Factorial is fight into for into they into doing to one when we simplify will get 30,000 2 40 This
