Answer 1

Answer:

1/8........

Step-by-step explanation:

1-(7/8)

1/8

Answer 2

Answer:

The correct answer is p(E) = 1/8

Step-by-step explanation:

probability:

Probability means the possibility of an occurrence. Its values are expressed between 0 and 1.

• Zero implies impossible events
• One implies possible (certain) events.

The total probability (P) of an event must be equal to one.

that is, the sum of the probabilities of the same event to occur and not occur must be equal to 1.

this can be represented as

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

In the given question,

probability of an event that is not occurring P(not E) = 7/8

probability of an event that is not occurring P(E) =?

we have,

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

P(E) = 1 - P(not E)

      = 1 - 7/8

      = 1/8

hence, P(E) = 1/8
