Consider a set S = {p, q,r,s, t} of Boolean variables. Let ϕ = p ⊕ q ⊕ r ⊕ s ⊕ t. Describe briefly the conditions under which ϕ is true. Use English and, if appropriate, standard (nonlogical) mathematical notation. (Hint: look at the symbol ⊕ itself. What’s p + q + r + s + t, treating true as 1 and false as 0 as in Exercises 3.23–3.26?)
