Question

if P(B)=1/3 compute P(not B)

Answer 1

P(not B) = 1 - P(B)

Answer 2

is P multiplied by B? if it is,

P*B = 1/3 *divide both sides by B
P*B/B = (1/3)/B
P = 1/(3B)

so there,, =)

Answer 3

[AI-generated answer — Explain Bot]

To compute P(not B), we can use the complement rule. The complement of an event B is the event that B does not occur, denoted as "not B."

The complement rule states that P(not B) = 1 - P(B).

In this case, we are given that P(B) = 1/3. Therefore, we can calculate P(not B) as follows:

P(not B) = 1 - P(B)
= 1 - 1/3
= 2/3

So, P(not B) is equal to 2/3.
