You are given the probability that an event will happen. Find the probability that the event will not happen.
1. P(E) = 0.7
2. P(E) = 0.36
3. P(E) = 1/4
4. P(E) = 2/3

Respuesta :

Answer:

1) 0.3

2) 0.64

3) 0.75

4) 0.33                              

Step-by-step explanation:

We are given the following probabilities. We have to probability of that event not happening.

That is we have to find the complement of the event,

Complement of event:

  • The complement of event E is represented as E'.
  • [tex]P(E') = 1 - P(E)[/tex]

1. P(E) = 0.7

[tex]P(E') = 1 - P(E) = 1 - 0.7 =0.3[/tex]

2. P(E) = 0.36

[tex]P(E') = 1 - P(E) = 1 - 0.36 = 0.64[/tex]

3. P(E) = 1/4

[tex]P(E') = 1 = P(E) = 1 -\dfrac{1}{4} = \dfrac{3}{4} = 0.75[/tex]

4. P(E) = 2/3

[tex]P(E') = 1 = P(E) = 1 -\dfrac{2}{3} = \dfrac{1}{3} = 0.33[/tex]
