Consider two pairs of grandparents. The first pair has 4 grandchildren and the second pair has 32 grandchildren. Which of the tw

schepotkina [342]

Answer:

The second pair of grandparents have approximately 12 to 19 boys as grandchildren.

Explanation:

The probability of a grandchild being a girl or a boy is same, i.e., $\frac{1}{2}$ .

The first pair of grandparents have 4 grandchildren.

The second pair of grandparents have 32 grandchildren.

If first pair of grandparents have between 40% to 60% boys as grandchildren then the number of boys are in the limit,

$(40\%\ of 4,\ 60\%\ of 4)=(1.6, 2.4)\approx(2, 3)$

Thus, the first pair of grandparents have approximately 2 to 3 boys as grandchildren.

If second pair of grandparents have between 40% to 60% boys as grandchildren then the number of boys are in the limit,

$(40\%\ of 32,\ 60\%\ of 32)=(12.8, 19.2)\approx(13, 19)$

Thus, the second pair of grandparents have approximately 12 to 19 boys as grandchildren.

So, it is clear that the second pair of grandparents are more likely to have between 40% and 60% boys as grandchildren.

Also according to the law of large numbers as the sample size increases the probability of an event gets closer to the theoretical probability.

Which part of the male reproductive system produces fluids that help sperm move?

Leni [432]

Answer: I believe it's the prostate.

Explanation:

Not 100% sure, but by this defenition of prostate, i'm more convinced it's this answer rather the others:

"The prostate gland is a male reproductive organ whose main function is to secrete prostate fluid, one of the components of semen. The muscles of the prostate gland also help propel this seminal fluid into the urethra during ejaculation"

So by that, we can see it pushes the semen through the body, whether by producing a liquid or force.
