The solution I have with me is:
Prob(mean - 2*σ < X < mean + 1.5*σ) = (0.5 - 0.0228) + (0.5 - 0.0668)
My question is how we got (0.5 - 0.0228) + (0.5 - 0.0668) ?

Assume that a random variable follows a normal distribution with a mean of 80 and a standard deviation of 24. What percentage of this distribution is not between 32 and 116?
My approach is to calculate the Probability for (mean...
Hi
I have a question.
Let X1 & X2 be stochastic variables and X1<=X2, then can we say E[X1]<=E[X2] or SD[X1]<=SD[X2]? why or why not?
Looking forward to some reply
Thanks!
Urgent Stochastic Calculus help!
Hi,
I am new to stochastic calculus and finding some difficulty in understanding things. How to approach the solutions for problem under the topics like martingale, linear diffusion SDEs, expectation of martingale, Ito stochastic integral formulas...
The question I have is
Which graph most closely represents the graph of a solution to the differential equation dy/dx=1+y^4?
I have 5 graphs as options. I have doubt in two. Both are same except one is passing thru origin & the other is not. The correct answer is the graph which is passing...
I have just tried to find out some good online tutorials on Rings. When I think of rings, an empty circle comes to my mind...nothing else. I want to know the explanations of each & every points mentioned above otherwise I wouldn't have written them because I have the correct answer.
How the group of symmetries of the regular pentagram is isomorphic to the dihedral group of order 10?
Suggest me some good basic isomorphism online tutorial.
