Chapter 5: Q 5.6 (page 215)

Define a collection of events $E_{a}, 0 < a < 1$ having the property that $P (E_{a}) = 1$ for all $a$ but $P (\underset{a}{\cap} E_{a}) = 0$
Hint: Let $X$ be uniform over $(0, 1)$ and define each $E_{a}$ in terms of $X$ .

Short Answer

Expert verified

Therefore, the collection of events $E_{a}, 0 < a < 1$ having the property that $P (E_{a}) = 1$ for all $a$ but $P (\underset{a}{\cap} E_{a}) = 0$

Step by step solution

Given information:

let $X$ be uniform over $(0, 1)$ .

Explanation:

Let $X ~ \cup (0, 1)$ and $E_{a} = \{X \neq a\}$ .

Explanation:

Thus, $\forall_{a} \in (0, 1), P (E_{a}) = P (X \neq a) = 1$ but $P (\underset{a}{\cap} E_{a}) = P (0) = 0$ .
