Applying the given probabilities, it is found that there is a 0.42 = 42% probability of watching a movie today.
These following <em>probabilities </em>involve a movie being watched today:
- 0.5 of 0.6(if it rains today).
- 0.3 of 1 - 0.6 = 0.4(if it does not rain today).
Hence, adding them:
0.42 = 42% probability of watching a movie today.

Answer:
The other rational number in the operation given is:
- <u>6/5</u>
Step-by-step explanation:
To obtain the number in the operation given, we're gonna represent the operation:
- r * 15/14 = 9/7
Where:
- r = the other rational number.
Now we are going to solve r to identify its value in numbers:
- r * 15/14 = 9/7
(We pass a number that is multiplying to the left of the equal, to divide to the right of the equal symbol)
As you can see, when we operate, <u>the result is 6/5</u>, and we can prove this multiplying as we had in the original equation, replacing r by 6/5:
- r * 15/14 = 9/7
- 6/5 * 15/14 = 9/7
- 9/7 = 9/7
In this form, we know the result is correct.
