6. After buying some groceries from the supermarket, your mother rides a multicab to go home. The multicab has two different routes A and B. If the multicab takes route A, your mother will be home no later than 7 PM with probability of 0.8, but if the multicab takes route B, then she will arrive at your house no later than 7 PM with probability of 0.7. Assume that the multicab driver prefers route B, and takes the route 70% of the time. If your mother arrives at 8 PM, what is the probability that her multicab took route A?
