First we have to find the areas of both circle using the formula

For larger circle,

For smaller circle,

Required probability

Correct option is the second option .
B) 43 because they increase 3
c) 32 because they decrease 7
First we need to determine the type of progression in the question.That's geometric progression. Because the pattern from one sequence to the others are about multiplying.
Second, determine the ratio of the progressionr = a₂/a₁
r = a₂ ÷ a₁
r = 1/2 ÷ 2
r = 1/2 × 1/2
r = 1/4
Third, determine the formula to know the recursive rulea₂ = a × 1/4
a₂ = 1/4 × a
Fourth, determine a₁. a₁ is the first term of the progressiona₁ = 2
Final answer:Recursive rule

a₁ = 2
Answer: a) 15625, b) 0.2, c) 625, d) 0.008.
Step-by-step explanation:
Since we have given that
a) 
As we know that

So, it becomes,

(b) 
So, it becomes,

(c) 
As we know that

So, it becomes,

(d) 

Hence, a) 15625, b) 0.2, c) 625, d) 0.008.
