I need help with this. It says basis of R³ but isn't it wrong? Aren't we supposed to find the basis of **v**, not R³?

So there we determine three vectors, **a,b,c** be the basis of **v**. In this case: **v**=[2, -1, 4]= -2**a**+3**b**+0**c**

**v**=[2, -1, 4]= -2[a1, a2, a3]+3[b1, b2, b3]+0[c1, c2, c3] Then we can create a system of equations, we won't need **c** though, because it is already zero

I was under the impression that in a normal continuous distribution, the probability of *X (some variable)* = Any specific value is 0. So the answer to this problem would be... 0%. But the answer states otherwise as 0.026, how come? And how did they get that answer? Thank you.
