The probability that can be chosen by Jake will be 33.5%.
How to calculate the probability?
The area of the whole dartboard will be:
= πr²
where r will be:
= 3 + (4 × 4)
= 3 + 16
= 19
Area = π(19)² = 361π²
The area of 30, 40, and 50 points will be:
= π × [3 + (2 × 4)]²
= 121π²
The probability will be:
= (361π - 121π) × 100
= 33.5%
