Q:

CD-ROM is a semiconductor memory.

A) TRUE B) FALSE
Answer & Explanation Answer: B) FALSE

Explanation:

"CD-ROM is a semiconductor memory" is a FALSE statement.


 


Compact Disc-Read-Only Memory, a type of optical disk capable of storing large amounts of data -- up to 1GB, although the most common size is 650MB (megabytes). A single CD-ROM has the storage capacity of 700 floppy disks, enough memory to store about 300,000 textpages.


 


Semiconductor memory is a type of semiconductor device tasked with storing data. There are two electronic data storage mediums that we can utilize, magnetic or optical.


 


Magnetic storage:


* Stores data in magnetic form.


* Affected by magnetic fields.


* Has high storage capacity.


* Doesn't use a laser to read/write data.


* Magnetic storage devices are; Hard disk , Floppy disk, Magnetic tape etc.


 


Optical storage:


* Stores data optically, uses laser to read/write.


* Not affected by magnetic fields.


* Has less storage than a hard disk.


* Data accessing is high, compared to a floppy disc.


* Optical storage devices are; CD-ROM,CD-R, CD-RW, DVD etc.


 


There is also volatile memory. This is memory that loses its data once power is cut off, while non-volatile memory retains data even without power.

Q:

A bag contains 4 red and 3 black balls. A second bag contains 2 red and 4 black balls. One bag is selected at random. From the selected bag, one ball is drawn. Find the probability that the ball drawn is red.

A) 23/42 B) 19/42
C) 7/32 D) 16/39
 
Answer & Explanation Answer: B) 19/42

Explanation:

A red ball can be drawn in two mutually exclusive ways

 (i) Selecting bag I and then drawing a red ball from it.

 

(ii) Selecting bag II and then drawing a red ball from it.

 

Let E1, E2 and A denote the events defined as follows:

E1 = selecting bag I,

E2 = selecting bag II

A = drawing a red ball

Since one of the two bags is selected randomly, therefore 

P(E1) = 1/2  and  P(E2) = 1/2

Now, PAE1 = Probability of drawing a red ball when the first bag has been selected = 4/7

  PAE2  = Probability of drawing a red ball when the second bag has been selected = 2/6

 Using the law of total probability, we have 

 P(red ball) = P(A) = PE1×PAE1+PE2×PAE2 

 

                          = 12×47+12×26=1942
