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:
DOG = 270
Step-by-step explanation:
270 × 3 = 810
_____
The only numbers that end in the same digit when multiplied by 3 are 0 and 5.
0×3 = 0
5×3 = 15
If G is 5, then you are looking for digits DO than give a product of 80 when multiplied by 3. 80 is not divisible by 3, so that doesn't work.
G must be 0.
Then the product of DO and 3 is 81, so DO = 81/3 = 27.
The solution is ...
D = 2
O = 7
G = 0
Answer:
B is correct
Step-by-step explanation: an infinite number of solutions means a coincident line...it is the same line
3y = 2x - 9...divide by 3
y = 2/3x - 3...hmm...same line as answer choice b....they are coincident lines and have infinite solutions
