A researcher reports that when groups of 4 children are randomly selected from a population of couples meeting certain criteria, the probability distribution for the number of girls is as given in the accompanying table

X P(x)
0 0.502
1 0.365
2 0.098
3 0.011
4 0.001


Determine whether a probability distribution is given, if one isn’t described, identify the requirements that are not satisfied. In those cases where a probably distribution is described, find its mean and stand deviation.

I think the mean is 2 and stand dev. is 1.414.

I'm supposed to translate into symbolic form and then find out whether it is valid or not.

Assume m and n represent particular, fixed integers.
If m is divisible by 6, then m is even.
But m is not even.
Therefore m is not divisible by 6.

After doing a truth table I think its VALID...am I right or wrong?

Okay I got a really good answer on my last question, but how would you solve the angle of a triangle if all you knew where the sides and that it is a 90 degree triangle.

I know sin, tan, or cos, but am blanking pls help!!

Could someone tell me if i solved this correctly? The question reads "find the derivative of f(x)= sec^3x (sec cubed x).

I got it to = 3sec^3x*tanx.

Im a calc2 student but Im trying to do a little more math on my own. A number theory book I have is talking of prime numbers and in this section they say you need to integrate 1/lnx from 0 to x. This is a non elementary function so parts, substitution, etc will not work. I know I have to express this as an infinite series but I dont know how to do this unless its a very simple function. (I can do geometric series expansions and the like but I dont know how to do this as 1/lnx)

Can anyone integrate 1/lnx from 0 to x and explain it detailed steps how they did everything. I want to understand how the function was expressed as a series and what function it gives you. (Since the upper bound is x it should give a function, not a number...right?) Thanks in advance.
