Answer:
99.9973 %
Step-by-step explanation:
This is a binomial probability distribution.
Since the probability of satisfactory welds = 97% = 0.97 and the probability of defective welds = 3% = 0.03.
Since there are 3 welds and we require at least one being defective, our binomial probability is
P(x ≥ 1) = 1 - P(x ≤ 0) = 1 - P(0) = 1 - ³C₀(0.03)³(0.97)⁰ = 1 - 1 × 0.000027 × 1 = 1 - 0.000027 = 0.999973 × 100% = 99.9973%
The maximum rate, r, that the scuba diver may descend is r≤ 11.2
Given the following parameters:
- Initial length = 14.7feet
If the scuba diver reaches a depth no more than 65.1 feet below sea level, then;
r ≤ (65.1 - 14.7)/4.5
r≤ 50.4/4.5
r≤ 11.2
Hence the maximum rate, r, that the scuba diver may descend is r≤ 11.2
