I  Omega  I = 6² = 36

A = { ( 5,6),(6,5), (6,6) }           [tex]\frac{5 + 6}{2} = \frac{11}{2} = 5,5 > 5[/tex]

I A I = 3

P ( A ) =[tex]\frac{3}{36} = \frac{1}{12}[/tex]

-----------------------

B = { ( 1,6),(2,5),(2,6),(3,4),(3 ,5),(3,6),(4,3),(4,4), ( 4,5),(4,6),(5,2),(5,3),(5,4),(5,5),  ( 5,6), ( 6,1),(6,2),(6,3),(6,4),(6,5), ( 6, 6 ) }

I B I = 21

P ( B ) = [tex]\frac{21}{36} = \frac{7}{12}[/tex]

====================

bo  np.  [tex]\frac{1 +6}{2} = 3,5 > 3[/tex]

28.

a = 8 cm      b = 15 cm

c =I AF I  = I BF I

c² = 8² + 15² = 64 + 225 = 289

c = [tex]\sqrt{289} = 13\\[/tex]

c = 13 cm

Obwód Δ ABF            

L = a + 2 c = ( 8 + 2*13 ) cm = 34 cm
