The probability that there'll be no defective will be 0.504.
<h3>How to calculate the probability?</h3>
Probability of A being defective = 0.2.
Probability of B being defective = 0.1
Probability of C being defective = 0.3.
The probability that there will be no defective will be:
= (1 - 0.2) × (1 - 0.1) × (1 - 0.3)
= 0.8 × 0.9 × 0.7
= 0.504
The probability that there'll be no defect is 0.504.
The probability that there'll be at least two defective part will be:
= (0.2 × 0.1) + (0.2 × 0.3) + (0.1 × 0.3)
= 0.02 + 0.06 + 0.03
= 0.11
The probability that there'll be at least two defects is 0.11.

Answer:
See below
Step-by-step explanation:
Distance = rate * time
= 65 m/hr * 2 1/4 hr = 146.25 miles
rate = distance / time
for Declan : rate = 146.25 miles / (2 hrs + 35/60 min) = 56.61 mph
