If two marbles are drawn at random. Then the probability that both marbles are blue is 42.42%.

<h3>What is probability?</h3>

Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.

A bag contains 12 marbles of which 4 are red and 8 are blue.

If two marbles are drawn at random.

Then the probability that both are blue will be

The favorable events will be

Favorable events = ⁸C₂

Favorable events = 28

The total events will be

Total events = ¹²C₂

Total events = 66

Then the probability will be

P = 28/66

P = 0.4242

P = 42.42%

Which Iink between two elements could you remove from the relation so that becomes a function?
OLEGan [10]

Answer:

Either (3,b) or (3,e) must be removed to form the above relation to be function.

Step-by-step explanation:

Given the relation between the elements of domain and range. we have to remove the link between two elements so that relation becomes a function.

A function is a relation in which each element in domain set maps into only one element of range set i.e one element can never have two images in range set.

Here, the element 3 in domain set maps into two element b and e in range set. Therefore, to form a function one link must be removed either

f(3)=b or f(3)=e

Hence, either (3,b) or (3,e) must be removed to form the above relation to be function.
