It’s known that a random variable X is distributed normally with E(X) = -1
and it’s also known that p(-4≤X≤-3)+p(1≤X≤2) = 0.3. Find p(-4≤X≤-3).
My work so far:
p(-4≤X≤-3) = p(1≤X≤2) , due to intervals (-4,-3) and (1,2) are symmetric...
Can anyone help guide me through this question? I' m having a tough time..
