A friend claims that it will rain today with probability 30% and tomorrow with probability four times as great as today. Which of the following is CORRECT? The claim can be true because it is more likely to rain tomorrow if we have rain today.
The claim cannot be true because raining tomorrow is not guaranteed. The claim can be true because it is possible to have rain tomorrow.
The claim cannot be true because any probability is between 0 and 1.

The claim cannot be true because any probability is between 0 and 1

Step-by-step explanation:

Probability is a concept used to mathematically provide a measure or determine the possibility that an event will occur. However, due to the nature of upcoming events, it is almost impossible to predict some events with absolute certainty, therefore, the chance of an event can be predicted based on the likelihood of the event occurring with probability values ranging from 0 to 1 or 0% to 100%. Where a value of 0 or 0% shows that it is certain that the event will not occur, while 1 or 100% indicates that it absolutely certain that an event will occur.

answer: -8.2562234e+13

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
