Coin Flip When doing a coin flip what pattern would you obse

Coin Flip:

When doing a coin flip, what pattern would you observe if everyone in the class were to bias their results to 5 heads/5tails? (on this one I don\'t understand the question. If everyone chose 5 heads/5tails wouldn\'t that be the only outcome? I\'m confused).

Which term refers to the 5h/5t (5 heads/5 tails). How many different ways can the combinations of 5 heads and 5 tails occur? In other words, what is the coeficcient for this term in the binomial equation? Derive this term using the binomial formula.

Probability:

Calculate the probability of having 10 boys.

If you have 7 children, Calculate the probability of having AT LEAST 5 boys.

A dog has a diploid number of 78 chromosomes. How many chromosomes would be expected in an egg cell produced by the dog? How many chromosomes would be expected in one of the dog\'s heart cells?

Albinism in humans is autosomal and fully recessive to normal color. A couple, who are both normal, have a duaghter who is albino and a son who is normal.

What is the probability that their normal son is a carrier of the albinism gene?

The couple wants to have 3 more children. What is the probability that they will have 3 normal girls?

Genetics:

Which division of meiosis (meiosis 1 or 2) is the Law of Independent Assortment carried out?

In the cross Aa Bb Cc Dd Ee x Aa Bb Cc dd Ee what proportion of offspring are expected to be homozygous recessive for all 5 genes?

In the same cross, what is the probability of offspring with the following genotype: AA Bb cc Dd ee?

Solution

COIN FLIP:

If we let the axis to be the number of heads, then we see one peak at 0 (all tails) and another peak at 5 (all heads).

This is what we see instead of a symmetric binomial distribution.

*********************

In the binomial equation, the coefficient of these terms are

5C0 = 1 (for all tails)
5C5 = 1 (for all heads)

As you can see, there is only one way that all of them are heads or all are tails, that is to get it consistently right from the start.
