Answer: The system will succeed when the first alarm rings or when the first one fails, but the second one rings. The probability of this is 0.98
The probability of system failure is 1-(probability of success)= 1-0.98= 0.02
Step-by-step explanation:
The amount paid to the man in the first year given the total he received in four years is $3,700.
<h3>Equation</h3>
- Amount paid in the first year = x
- Amount paid in the second year = (x + 500)
- Amount paid in the third year = x + 500 + 500
= (x + 1000)
- Amount paid in the fourth year = x + 500 + 500 + 500
= (x + 1500)
Total payment = first year + second year + third year + fourth year
x + (x + 500) + (x + 1000) + (x + 1500) = 17,800
x + x + 500 + x + 1000 + x + 1500 = 17800
4x + 3000 = 17,800
4x = 17,800 - 3000
4x = 14,800
x = 14,800/4
x = $3,700
Therefore, $3,700 was paid to the man in the first year.
