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)=
P(E')= 1-P(E)
P(E)=1-P(E')
Would #2 just be 16/35?
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.
