Question

The theoretical probability of choosing Event A is 2

—

7

. What is the

theoretical probability of not choosing Event A?

Answer 1

Answer:
`(5)/(7)`

Explanation:

Given

The theoretical probability of choosing an event A is
`(2)/(7)`

The sum of the probability of occuring and non-occuring of an event is always equal to 1.

So, the probability of non choosing Event A is

`\Rightarrow 1-(2)/(7)\\\\\Rightarrow (7-2)/(7)\\\\\Rightarrow (5)/(7)`
