The problem can be solved using hypergeometric distribution, but for relatively simple cases, we can work it out by reasoning.
Given d=539 defectives in a batch n=1651, and the sampling size is 3.
This means that there are 1651-539=1112 good items.
The probability of picking three good items is therefore
P(GGG)=1112/1651 * 1111/1650 * 1110/1649
=4155544/13612495
=0.30527 (to 5 places of decimal)
Answer: the probability of passing the test is 0.30527 (to 5 decimal places)
Answer:
Step-by-step explanation:
First get rid of the parenthesis
Next simplify the variables
One number is 26 the other is 23
x+y=49
Y=x+3,X (now substitute it in the equation)
x+3+x=49
2x+3=49
2x=46. X=23
Y=x+3. Y=23+3 =26 for checking 23+26=49
Answer and Step-by-step explanation:
The domain is all real numbers <u>except</u> 9 (positive)
This is because we can't have 0 in the denominator, and when x equals 9, then the denominator is 0. Anything divided by 0 is undefined, which is why 9 (in this equation) is <u>not</u> included.
