Problem
Renzhi takes a lift to school in the morning with either Aline (20% of the time), Brett (35% of the time) or Carlos (45% of the time). The probability of being late in each case is: 0.05 with Aline, 0.16 with Brett and 0.02 with Carlos. Given that Renzhi is late for school, what is the probability that he took a lift with Aline?
