Salinity in Quebec river is a combination of tides and rain. Rain that diluted the salt occurs about 10% of the time, while the non salty outgoing tides occurs twice per day. You take your dog for a walk down by the river at random during the weekend and notice that he'll drink from the river 30% of the time when the salt is sufficiently low. Questions Given that the overall probability of rain remains 10 % what is the probability of rain during a non tide period? please send me answer in typed form strictly prohibited handwritten solution
