Two events, A and B, are disjoint. What is the probability that both A and B will occur at the same time?

solniwko [45]

ANSWER

$P(A\cap B)=0$

EXPLANATION

If the two events are disjoint, then they are mutually exclusive.

This means that their intersection is zero.

Therefore

$n(A\cap B)=0$

This implies that,

$P(A\cap B)= \frac{n(A\cap B)}{n(U)}$

$P(A\cap B)= \frac{0}{n(U)} = 0$

The probability that the two events will occur together is 0, which means an impossibility.

A news outlet posted a poll on its website asking what type of drink people preferred. Identify the problem with taking a survey

Jet001 [13]

Since the news outlet posted a poll on its website, it would be biased on the fact that it's on the website. Some people don't read the website, or don't have a computer or internet.
