Question:
If a sample of 2 hammer is selected
(a) find the probability that all in the sample are defective.
(b) find the probability that none in the sample are defective.
Answer:
a
b
Step-by-step explanation:
Given
--- hammers
--- selection
This will be treated as selection without replacement. So, 1 will be subtracted from subsequent probabilities
Solving (a): Probability that both selection are defective.
For two selections, the probability that all are defective is:
Solving (b): Probability that none are defective.
The probability that a selection is not defective is:
For two selections, the probability that all are not defective is:
Answer:
Refractive index of a medium depends upon the refractive index of the surroundings
Answer:
y = 1
Step-by-step explanation:
y is inversely proportion to x means that ,
y ∝ 1/x or ,
When we remove the proportionality sign we get,
now we know the point is (2 , 3) which means it corresponds to (x , y) which furthermore means y=3 when x=2,
so we insert these values and get the value of k.
now the equation becomes,
now we need to find y when x is 6 so just replace x with 6
so we get the value of y is 1
