Answer:
1) P(E) = 1 - 0.14 = 0.86
2) P(E) = 1 - 0.92 = 0.08
3) P(E) = 1 - 17/35 = 18/35
4) P(E) = 1 - 61/100 = 39/100
Step-by-step explanation:
The probability that an event will happen equals one minus the probability that an event will not happen.
P(E) = 1 - P(E') ......1
Where;
P(E) is the probability that an event will happen.
P(E') is the probability that an event will not happen.
1. P(E') = 0.14
Applying equation 1
P(E) = 1 - 0.14 = 0.86
2. P(E') = 0.92
P(E) = 1 - 0.92 = 0.08
3. P(E') = 17/35
P(E) = 1 - 17/35 = 18/35
4. P(E') = 61/100
P(E) = 1 - 61/100 = 39/100
