It is important to note that all the information's required are already given in the question
Probability that a day will be hot = 0.15 + 0.10
= 0.25
Probability that a day will be sunny = 0.15 + 0.30 + 0.10
= 0.55
Adding the above two probabilities, we get = 0.25 + 0.55
= 0.80
Now
Probability that a day will be both hot and sunny = 0.15
So
Probability that a day was hot or sunny = 0.80 - 0.15
= 0.65
I hope the procedure is clear enough for you to understand.

Answer:
b
Step-by-step explanation:
The probability (PB) is .4 or 4/10 or 2/5.
So, we'd do a proportion.
2/5=x/6
Cross multiply.
5x=12
Divide by sides by 5.
x=2.4
We round up to account for the .4
so b
I can't answer c right now, but I'll come back once my class is over :)
here we have 3X to 5 seventh power in radical form
we need write this in radical form we knwo that 
so ![3x^{5/7} =\sqrt[7]{3x^{5}}](https://tex.z-dn.net/?f=%203x%5E%7B5%2F7%7D%20%3D%5Csqrt%5B7%5D%7B3x%5E%7B5%7D%7D%20%20%20)
this will be the radical form .
