Question

if P(E)=0.4 find P ( not E )​

Answer 1

Answer:

P(E)+P(not E) =1

thus P(not E) =1-0.4

thus P(not E) = 0.6

Answer 2

Answer:

The value of P (not E) is 0.60.

Step-by-step explanation:

The complement of an event, say A, is the probability of that event not occurring.

It is denoted by $A^{c}$ and is known as (not A).

Then the probability of (not A) is: $P(A^{c})=1-P(A)$

Given:

P (E) = 0.40

Then the probability of the complement of event E is:

$P(E^{c})=1-P(E)\\=1-0.40\\=0.60$

Thus, the value of P (not E) is 0.60.
