Answer:

Before rolling a die you do not know the result. This is an example of a random experiment. In particular, a random experiment is a process by which we observe something uncertain. After the experiment, the result of the random experiment is known. An outcome is a result of a random experiment. The set of all possible outcomes is called the sample space. Thus in the context of a random experiment, the sample space is our universal set. Here are some examples of random experiments and their sample spaces:

Random experiment: toss a coin; sample space: S={heads,tails} or as we usually write it, {H,T}.

Random experiment: roll a die; sample space: S={1,2,3,4,5,6}.

Random experiment: observe the number of iPhones sold by an Apple store in Boston in 2015; sample space: S={0,1,2,3,⋯}.

Random experiment: observe the number of goals in a soccer match; sample space: S={0,1,2,3,⋯}.

When we repeat a random experiment several times, we call each one of them a trial. Thus, a trial is a particular performance of a random experiment. In the example of tossing a coin, each trial will result in either heads or tails. Note that the sample space is defined based on how you define your random experiment. For example,

Example  

We toss a coin three times and observe the sequence of heads/tails. The sample space here may be defined as

S={(H,H,H),(H,H,T),(H,T,H),(T,H,H),(H,T,T),(T,H,T),(T,T,H),(T,T,T)}.

Our goal is to assign probability to certain events. For example, suppose that we would like to know the probability that the outcome of rolling a fair die is an even number. In this case, our event is the set E={2,4,6}. If the result of our random experiment belongs to the set E, we say that the event E has occurred. Thus an event is a collection of possible outcomes. In other words, an event is a subset of the sample space to which we assign a probability. Although we have not yet discussed how to find the probability of an event, you might be able to guess that the probability of {2,4,6} is 50 percent which is the same as 12 in the probability theory convention.

Outcome: A result of a random experiment.

Sample Space: The set of all possible outcomes.

Event: A subset of the sample space.

Union and Intersection: If A and B are events, then A∪B and A∩B are also events. By remembering the definition of union and intersection, we observe that A∪B occurs if A or B occur. Similarly, A∩B occurs if both A and B occur. Similarly, if A1,A2,⋯,An are events, then the event A1∪A2∪A3⋯∪An occurs if at least one of A1,A2,⋯,An occurs. The event A1∩A2∩A3⋯∩An occurs if all of A1,A2,⋯,An occur. It can be helpful to remember that the key words "or" and "at least" correspond to unions and the key words "and" and "all of" correspond to intersections.

Dmitriy789 [7]

Answer:

Vascular system - phloem and xylem

Explanation:

The phloem is responsible for translocating nutrient and sugars which are produced by the leaves to areas og the plant that are metabolically activew while the xylem cell wall transport water gom the root to the leaves.

However, a plant may have many xylem tissues extending up to the plant.

What’s the difference between heal cells and human cells?
Vesnalui [34]

Answer:

HeLa cells, like many tumours, have error-filled genomes, with one or more copies of many chromosomes: a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.

Why were bacteria given their own Kingdom?
lozanna [386]
1 Answer. Mandira P. With the discovery of electron microscope, biologists realised that it did not make any sense to include prokaryotic world of bacteria in kingdom protista with single celled eukaryotic organisms. Hence a separate kingdom, Monera, was created.
