Question

a water ballon is to be randomly dropped along a 1 mile long line that stretches across a practice target zone. the target zones center is the midpoint of the line

Answer 1

It seems like the question is not complete. So, I will asume that the complete question is: " A bomb is to be dropped along a mile-long line that stretches across a practice target. The target center is at the midpoint of the line. The target will be destroyed if the bomb falls within a tenth of a mile on either side of the center. Find the Probability that the target is destroyed if the bomb falls randomly along the line."

Explanation:

The total of possible cases is the length of the line = 1 mi ;

The favourable cases are the two lengths of 0.1 mi = 0.2 mi ;

Assuming the bomb has no bias for any point ,

the probability of favourable cases' occurrence is 0.2/1 = 0.2
