It's crucial to recognize that all necessary information is already presented in the question
The likelihood of a day being hot equals 0.15 + 0.10
= 0.25
The likelihood of a day being sunny amounts to 0.15 + 0.30 + 0.10
= 0.55
Combining the two probabilities, we find = 0.25 + 0.55
= 0.80
Now
The probability of a day being both hot and sunny is 0.15
Thus
The probability of a day being either hot or sunny = 0.80 - 0.15
= 0.65
I trust this explanation is clear enough for your understanding.
Addends refer to the numbers being summed in an equation.
Their arrangement only matters if parentheses are utilized to modify the usual Order of Operations.
For example:
2 - (8 + 3) in this case, 8 and 3 must be grouped first before tackling the subtraction.
Any addition scenario without parentheses can similarly function where the grouping is irrelevant.
E+7 indicates 10 raised to the power of 7, which entails shifting the decimal 7 places to the right, resulting in approximately 38200000.0.
To tackle this problem, you can use the same method from the prior situation.
Option 1: 2/(1/16 + 1/65) = 25.7 mpg
Option 2: 2/(1/14 + 1/85) = 24.0 mpg

Like before, enhancing the least efficient vehicle yields the best outcome.
