Odpowiedź:
N = ( 14 nad 4 ) = [tex]\frac{14 !}{4 ! * 10 !} = \frac{11*12*13*14}{1*2*3*4} =[/tex] 11*13*7 = 1001
a) n = ( 8 nad 2)*(6 nad 2) = [tex]\frac{8 !}{2* 6 !} * \frac{6 !}{2* 4 !} =[/tex] 28*15 = 420
P( A) = [tex]\frac{420}{1001}[/tex]
==========
b) n = 8* ( 6 nad 3) = 8 * [tex]\frac{6 ! }{3 ! * 3 !} =[/tex] 8*[tex]\frac{4*5*6}{6} =20[/tex] * 8 = 160
P( A) = [tex]\frac{160}{1001}[/tex]
