The answer is TRUE
There are only two possible outcomes
- Tomorrow it rains.
- Tomorrow it does not rain.
Thus the probability of one outcome dictates the probability of the other.
For example, imagine that
<em>P(It will rain tomorrow) = 1 </em><em> </em>(This means that you are 100% sure it will rain)
Then you can assure that
<em>P(It will rain tomorrow) = 1 - P(It will not rain tomorrow)</em>
<em>P(It will not rain tomorrow) = 0</em>
Answer:

Step-by-step explanation:
Z-score for 30 = (30 - 25) / 5.8 = 0.8621
z-score for 20 = (20 - 25) / 5.8 = -0.8621
:
Note find probabilities from z-tables
:
Probability ( 20 < X < 30 ) = 0.8051 - 0.1949 = 0.6102
