Answer:
Right option is C. Events A and B are not independent because P(B|A) ≠ P(B).
Step-by-step explanation:
We have given,
Probability of contamination in batch 1 of a drug (event A) ,P(A) = 0.16
Probability of contamination in batch 2 of the drug (event B), P(B) = 0.09
Also,
Probability of contamination in batch 2, given that there was a contamination in batch 1, P(B/A) = 0.12
Since P(B/A) ≠ P(B), Therefore events A and B are not independent events.
Right option is C. Events A and B are not independent because P(B|A) ≠ P(B).
Answer:
smallest number of chickens= 3
Step-by-step explanation:
In this question the given formation is:
two chickens in front of a chicken
the total number of chickens are 3
two chickens behind a chicken
the total number of chickens are 3
a chicken between two chickens
the total number of chickens are 3
So, the smallest number of chicken that can be required to make this formation will be 3.
So, if we consider that the chickens are walking in a straight line, two (2nd and 3rd) chickens will be behind the 1st chicken, two chickens( 1st and 2nd) will be in front of the last (3rd) chicken and one (2nd) chicken is in the middle of two (between 1st and 3rd) chicken.

Hi. This can be answered with a ratio. If 1 litre = 1 kilogram then 1.75 litres = unknown grams. So we know that there are 1000 grams in 1 kilogram so 1.75 litres would be 1750 grams. Its just a matter of cross multiplying.
Answer:
The height of the kite is equal to
Step-by-step explanation:
see the attached figure to better understand the problem
The point A is your hand and point C is the kite
we know that
In the right triangle BCD
---> by SOH (opposite side divided by the hypotenuse)
substitute the given values
solve for CD
The height of the kite is equal to
