Answer:
P(X=3) = 0.2013
Step-by-step explanation:
After taking and tagging the first 20 birds, then we have a proportion of 20% of tagged birds within the population, that is


Supposing that the probability (0.20) of capturing a bird <em>remains constant</em>, we may resolve it as it follows:
Capturing 10 birds can be considered as a binomial experiment with a success probability p = 0.2
Let,
be the expression of the binomial distribution, for our case we have:
p=0.2
x = 3
n=10
Then,


Therefore, the probability that exactly 3 of the 10 birds in the new sample were previously tagged is 20.13%
Don't hate me if I'm wrong but I think the first one is 76 but I couldn't find out the second line.

Answer:
(-5) is smallest integer to be added.
Step-by-step explanation:
In the given expression we have to identify the smallest integer to be adeed so that it is divisible by (m+1).
If we divide the expression then we get quotient (-2m²+3m-4) and the remainder is +5.
Therefore we can say that if we subtract 5 from the given expression it will be divisible by (m+1).
So the answer is (-5) is the smallest integer to be added.
