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%
Answer:
Step-by-step explanation:
12/24 reduces to 1/2, whereas 3/4 does not reduce. This pair of ratios does not form a proportion.
If both ratios reduced to the same common value, that would represent a proportion.
Divide 42 by 2 and get 21.
