Step-by-step explanation:

Problem 4a

You have 6 numbers on the cube, a bag with 4 letters and a spinner with 3 letters

The total number of results is

6 * 4 * 3 = 72

Problem 4b

P(A,3,Q) = (1/3)(1/6)(1/4) = 1/72

Problem 4c

A and Q remain the same. 1/3 and 1/4

Not rolling a 6 is a little different. Success will result in a 1 2 3 4 5 being thrown. That's 5/6

So the results are 1/3 * 1/4 * 5/6 = 5/72

Ulleksa [173]

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

$p=\frac{n}{N}$

$p=\frac{20}{100}=0.20$

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, $P(X=x)=nCx*p^{x}*(1-p)^{n-x}$ be the expression of the binomial distribution, for our case we have:

p=0.2

x = 3

n=10

Then,

$P(X=3)=10C3*0.2^{3}*0.8^{10-3}$

$P(X=x)=0.2013$

Therefore, the probability that exactly 3 of the 10 birds in the new sample were previously tagged is 20.13%
