By A ⊂ B (read, ” A is a subset of B ”) we mean that every point that is in A is also in B. If A ⊂ B and B ⊂ A, then A a ...

Hence, in this sequence, for every i, the probability that ti > 2 is approximately equal to the probability that a normally distributed random variable with 0 average and unit standard deviation exceeds the value 2 – i.e., to ≈ 2.5% = 1/40. Thus, on average, one out of 40 iterations leads to t > 2. ...
