Among the following propositions:  
\\(①\\) If \\((x-2)^{5}=a_{5}x^{5}+a_{4}x^{4}+a_{3}x^{3}+a_{2}x^{2}+a_{1}x+a_{0}\\), then \\(a_{1}+a_{2}+a_{3}+a_{4}+a_{5}=31\\);  
\\(②\\) If the random variable \\(X\\) follows the normal distribution \\(N(1,2)\\), then \\(P(X < 0)=P(X > 2)\\);  
\\(③\\) If the expansion of the binomial \\((x+ \dfrac {2}{x^{2}})^{n}\\) has a sum of coefficients equal to \\(243\\), then the coefficient of \\(x^{-4}\\) in the expansion is \\(40\\);  
\\(④\\) If the numbers obtained from rolling a die twice are \\(m\\) and \\(n\\), respectively, and the angle between the vector \\( \overrightarrow{a}=(m,n)\\) and the vector \\( \overrightarrow{b}=(1,-1)\\) is denoted as \\(θ\\), then the probability of \\(θ∈(0, \dfrac {π}{2}]\\) is \\( \dfrac {7}{12}\\).
