Domain

In simple mathematics terms, a domain is defined as the space on which all the possible inputs for the function will lie. It can also be expressed as a set of departures for the required function.

In a rural area, there is a road that connects location X and location Y, however this road cannot be passed about 50% of the time due to floods. There is another route that goes to location Z. The road from location X to Z is only passable 75% of the time and the road from location Z to Y is only passable 70% of the time. Furthermore, if the road between location X and Z is passable, then the road travelling from Z to Y is passable 80% of the time. If the route from location X to Y to Z is passable, then the route directly from location X to Y is passable 80% of the time. What is the probability of travelling from location X to Y? If during the night a flood makes the road from X to Z impassable, what is the probability that the traveller can still travel from Z to Y? Please answer completely will give rating surely
