Can dogs regulate their body temperature?.
Crank

Dogs can regulate their body temperature by the time they are 7 weeks old.

Dogs have remarkable internal mechanisms that maintain their body at the proper temperature at all times, irrespective of the air temperature because they are unable to endure large changes in their body temperatures.

Dogs do not perspire through the skin as people do due to their insulating coats.

A comfortable winter temperature for most dogs is between 68 and 72 degrees. The same considerations mentioned above for selecting a safe, comfortable summer temperature setting apply to selecting a winter thermostat setting.

A man and a woman have three children, all males. What is the probability that their next child will be a girl?.
ikadub [295]

Given what we know, we can confirm that the couple in question has a 50% chance that their next child will be a girl.

<h3>Why are the odds 1/2 ?</h3>

This has to do with the fact that each child that the couple has is an independent event. While it is true that it is unlikely for the same event to occur many times in succession, the previous events do not influence the outcome of the next child.

Therefore, given that a child can be either male or female when born, the couple in question has a perfect 50% chance for their next child to be a girl.
