i dont get it please help us

Answer: 70%</h3>
Reason:
Subtract the given probability from 100% to get the chance that it doesn't rain. So 100% - 30% = 70%
This is because we have two outcomes: it rains or it doesn't rain.
The probability of each outcome must add to 100%.
I have a solution here wherein instead of A(3) it is A(4):
<span>Plugging the numbers into the equation we get 4x4x3.14 which is 50.24
</span>
I hope you could use my method for solving the A(4) in solving the A(3)

Step-by-step explanation:
Givens
Let a = the first number
Let b = the second number
Equations
a + b = 39
b = 1/2 * a + 6
Put the second equation into the first one
a + 1/2 * a + 6 = 39 Simplify the left.
(3/2)a + 6 = 39 Subtract 6 from both sides
(3/2)a + 6 - 6 = 39 - 6 Combine
(3/2)a = 33 Multiply both sides by 2
3a = 33*2
3a = 66 Divide both sides by 3
3a/3 = 66/3
a = 22
b = 1/2 a + 6
a = 22
b = 1/2 * 22 + 6
b = 11 + 6
b = 17
Check
22 + 17 = 39
