Question

1.) P(E) = 0.7. Find the probability that the event WILL NOT happen.

P(E’)=

2.) P(E') = 17/35. Look for the probability that the event WILL happen.
Put answer is a/b form.

P(E)=

Answer 1

P(E')= 1-P(E)

P(E)=1-P(E')

Answer 2

Would #2 just be 16/35?

Answer 3

[AI-generated answer — Explain Bot]

To find the probability that an event will NOT happen, you can subtract the probability of the event happening from one.

1.) Given that P(E) = 0.7, we can find P(E') as follows:

P(E') = 1 - P(E)
P(E') = 1 - 0.7
P(E') = 0.3

Therefore, the probability that the event will NOT happen is 0.3.

2.) Given that P(E') = 17/35, we can find P(E) as follows:

P(E) = 1 - P(E')
P(E) = 1 - (17/35)
P(E) = (35/35) - (17/35)
P(E) = (35 - 17)/35
P(E) = 18/35

Therefore, the probability that the event WILL happen is 18/35.
