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.

A. The quantity of 10-boards that Peter purchases is equal to n divided by 10. Consequently, each of the 10-boxes will receive two boxes of nails. After purchasing n boards, the formula for the number of boxes of nails Peter will have will be,

N = (2)(n/10)

When simplified,

N = n/5

b. If the total number of boards is 90, then,

N2 = (90/10)(2)(100 nails/box)
N2 = 1800

Final Answer: 1800
