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:14
Step-by-step explanation:
7*2=14
300 parents
3/4 = x/400, and we are trying to find x.
Multiply the numerator and denominator of 3/4 each by 100 to make the denominator equal 400. This gives 300/400. So, 300/400 = x/400.
Multiply both sides of the equation by 400 to cancel out the division. This gives you 300 = x, so 300 parents said yes to the survey.
