The lifetime X in hours of a brand electronic component is an exponential random number with probability density function fx(x) = e 100 1 100 if x ≥ 0, 0 Otherwise. Four of these electronic components operate independently in an equipment. The equipment fails to work if and only if at least two of these electronic components fail. 1. Find the probability q that the equipment will work for at least 230 hours. 9 = 0.0037
