Answer:

the probability of occurance of event E is 0.09

Step-by-step explanation:

Given:

Probability of non - occurrence of event E in 0.91.

To Find:

Probability of occurance of event E

Calculation:

We know that,

Probability of Occurrence of an event + Probability of non-occurance of an Event = 1

Here the probability of non occurance of event E is 0.91

so, the probability of occurance of event E is = 1 - 0.91 = 0.09

Hence, the probability of occurance of event E is 0.09 (ans.)

[tex]if \: the \: probability \: is \: 0.91 \\ then \: p(e) = 1 - given \: probability \\ = 1 - 0.91 \\ = 0.9 \: answer. \\ hope \: it \: help.....[/tex]
