Consider families with two children, assuming equal probability for both genders. Let A be the event that the chosen family has at most one boy, B be the event that the chosen family has a boy and a girl and C be the event that either the chosen family has two boys or two girls.

a) Is P(AB) = P(A)P(B)? Are A and B independent? Are they mutually exclusive?

b) Is P(BC) = P(B)(C)? Are B and C independent? Are they mutually exclusive?

However, prove that if A and B are independent events and P(A)>0 and P(B)>0, then A and must be not mutually exclusive. (A very simple proof consists of one line only)

This is sort of not what the question was. I was a sixth grader during the past year and I am going into 8th grade math this september. Can you please give me a few problems to work on? I can do some algebra, 2 variables are tricky, fractions are great. Thank you for your effort. :)

Sitting under a tree is cooler than sitting under a sheet of cloth, for example. Why should that be?

This question was actually already asked 2 weeks ago, but I wasn't happy with the answer. The answer suggested then was that wind can blow easier in the tree shade, which I did not find convincing. I have two ideas:

(1) The tree shade is thicker, there are lots of leaves, so it insulates better

(2) The tree has to keep itself relatively cool to continue photosynthesis, so it cannot transfer as much heat downwards.

I think that explanation 2 is correct. Explanation 1 would only delay the time it takes for the heat to be transferred down, not eliminate it altogether.

I would be grateful for any alternative explanations, or supporting evidence for the explanations I thought of.

Thanks! Eyal

I am not very experienced with each Tarot card since I have only read a Tarot Reading book for beginners. That's why I feel a bit confused reading for anyone else.
How should I practice reading to understand a card's meaning deeper for each situation? How did you start it?
Thanks everyone.
