Which one of the following statements is True? Buffon’s Needle Problem approximates the Natural Logarithm Base. Probability is long run frequency. For any two events A and B, P(A or B) is less than or equal to P(A) + P(B). The Mode can be determined for a Box Plot. Probability equals the number of favorable outcomes divided by the number of unfavorable outcomes in a Sample Space.
