In a certain population, 99% of the people have Rh-positive blood. Suppose that two people from this population marry. What is the probability that they are both Rh-negative, thus making it inevitable that their children will be Rh-negative?

The probability that both will be Rh-negative out of 99% Rh-positive is 0.01 x 0.01 = 0.0001.

Explanation:

The population contain 99℅ of Rh-positive. This represent almost all of the people.

However, there is still 1℅ chance of having an individual of Rh-negative.

Both of them will have the probability of 1℅ of having Rh-negative(0.01).

Therefore, Pr(Rh-negative AND Rh-negative) = 0.01 x 0.01. The result is approximately equals zero.

The both parents having Rh-negative, will have a dominant Rh-negative blood passed to their children, only recessive Rh-positive of 25℅ chance.

Since the chance of Rh-negative blood passed to their children is 75℅, it is inevitable that their children will be Rh-negative

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
