Consider a woman whose brother is afflicted with hemophilia, which implies that the woman’s mother has the hemophilia gene on one of her two x chromosomes. thus there is a 50-50 chance that the woman’s mother has passed on the bad gene to her. the woman has two sons, each of whom will independents inherit the gene from one of her two chromosomes. if the woman herself has a bad gene, there is a 50-50 chance she will pass this on to a son. suppose that neither of her two sons is afflicted with hemophilia. what then is the probability that the woman is indeed the carrier of the hemophilia gene? what is the probability if she had a third son who also is not afflicted?

33.33% and 25%

Step-by-step explanation:

If the woman has a 50-50 chance to pass on the disease to her children, then 1 out of 2 children may have the disease.

As she has two children and none of them have the disease, this reduces the chances that the woman is the carrier of the hemophilia gene  to 1 out of 3, that is, 1/3 = 0.3333 or 33.33%.

After having a third son without the disease, the chances reduce to 1 out of 4, or ¼ = 0.25 = 25%

In this case the chances that the woman is the carrier of the hemophilia gene is 25%

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
