Question 5 Find the indicated probability. Round to the nearest thousandth. A sample of 4 different calculators is randomly selected from a group containing 11 that are defective and 25 that have no defects. What is the probability that at least one of the calculators is defective?

Given \( f \) and \( g \) as defined below, determine \( f+g, f-g, f g \), and \( \frac{f}{g} \). Using interval notation, report the domain of each result. \( f(x)=x^{2}-5 x \) and \( g(x)=x+6 \) (a) \( (f+g)(x)=\square \) Domain of \( (f+g)(x): \) (b) \( (f-g)(x)=\square \) Domain of \( (f-g)(x): \) (c) \( (f g)(x)=\square \) Domain of \( (f g)(x): \) (d) \( \left(\frac{f}{g}\right)(x)=\square \) Duestion Help: \( (x) \)
