The probability that a member regularly uses the golf course is 0.67, and the probability that a member regularly uses the tennis courts is 0.47. The probability that a member regularly uses neither of these facilities is 0.06. Therefore, the probability that a member regularly uses at least one of the golf or tennis facilities is 1 - 0.06 = 0.94.
