Most hospitals now have signs posted everywhere banning cell phone use. These bans originate from studies on earlier versions of cell phones. In one such experiment, out of 510 tests with cell phones operating at near-maximum power, 160 disrupted a piece of medical equipment enough to hinder interpretation of data or cause equipment to malfunction. What is an estimate of the probability that a randomly selected cellphone will disrupt a piece of medical equipment?
