Considere la sucesión (dk) con k>=1 definida por d1 = 9/10 ; d2 = 10/11 ; dk = d(k-1) * d(k-2); k >= 3: Usando inducción matemática fuerte demuestre que 0 < dn <= 1; Para todo n>=1:

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
