Probabilityis simply how likelysomethingis tohappen. Whenever we’re unsure about theoutcomeof an event, we can talk about the probabilities of certainoutcomes—how likely they are. The analysis of events governed by probability is calledstatistics.probabilityof an event is a numberbetween0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicatescertainty.Given:probabilitythat itrainsin London on anyparticularday is 0.4.probabilityof itrainingthe following daydecreasesto 0.25.probabilitythat itrainstoday= 0.2 * 0.4 = 0.08probabilitythat itdoesn’train todays= 0.4*0.4 = 0.16probabilityhere:#SPJ1
