@vidyarthi No,No bro
I couldn't prepare much
2.3 how would I do?
1. is wrong. right? It is not continuous anywhere.
2. true. It is true. since it is =0 (a.e)
3.It is true. since it is discontinuous only at single point $x=0$
@Nobodyrecognizeable bad in probability theory.

@Nobodyrecognizeable The problem regarding probability is straightforward. A drawing of the coordinate axes(2D plane) is quite helpful. The first such step has probability $1$. The second such step has probability $\frac{3}{4}$ since retracing the step would not take us beyond the circle in $3$ steps. The third step is a bit more tedious to calculate, but after taking each possibility into account, the probability of the desired step is
$4\times \frac{3}{4}\times\frac1{16}+8\times\frac1{2}\times\frac1{16}=\frac{7}{12}$. Now, multiplying the probabilities of each step gives us $\frac{7}{16}=0.4375$, which is the desired answer
