It you be 3/9 which is simplified as 1/3

Answer:

The chances of drawing a green card on your first try is 1/3

Explanation:

It is given that,

No. of black cards, n₁ = 3

No. of white cards, n₂ = 3

No. of green cards, n₃ = 3  

We have to find the probability of drawing a green card on the first try. Probability is given by :

P=\dfrac{no\ of\ favorable\ outcome}{total\ no\ of\ outcomes}

Here,

Total no of outcomes are 9 and no of favorable outcome is 3

So, P=\dfrac{3}{9}=\dfrac{1}{3}

Hence, the correct option is (d) " 1/3 ".

Over [174]

In areas where the walls are frequently washed, conduit should be mounted with a 1/4 inch air space between the wall and the conduit.

Conduits are the structures that are hollow and cylindrical like a pipe, channel or tube through which any material can pass. The material can be electrical wires, gases or even water. Therefore, the functions of conduits is to mediate the transport of materials from one place to another.

These conduits can be rigid or flexible depending upon their use and the material to be transported. Care should be taken when these conduits are embedded inside the wall that they are not very close and in contact with the wall otherwise the conduits may get damaged.

One gene in the human genome may be expressed at a much higher level than another. Can differences in types of cis elements pres
Oksana_A [137]

Answer:

No, CREs usually don't account for differences in gene expression levels.

Explanation:

<em>Cis</em>-regulatory elements (CREs) are non-coding DNA regions that regulate adjacent gene <em>transcription</em>. They usually do it by binding to transcription factors. They are in charge of influencing the rate of which transcription occurs, and less with how much a gene is expressed. On the other hand, trans-regulatory elements are DNA sequences that encode for upstream regulators that can modify or regulate <em>gene expression levels</em>.

Therefore, cis elements are not really in charge of expression levels, mostly transcription rates of single genes, rather. Trans elements are more involved in expression levels.
