Given:
The pair of composite numbers: 10 and 15
To find:
The greatest common factor (GFC) for the given pair of composite numbers.
Solution:
Two composite number are 10 and 15.
The factor forms of these two numbers are
It is clear that the common factor is 5 in both factor forms. So, the greatest common factor is
Therefore, the greatest common factor of 10 and 15 is 5.
The correct answer is option B which is P ( A|B) will be ( 4 / 9 ).
<h3>What is probability?</h3>Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Given that:-
The total sample will have 9 numbers
S = { 1,2,3,4,5,6,7,8,9} = 9
Even Number = { 2,4,6,8} = 4
Odd Number = { 1,3,5,7,9} = 5
P ( A ) = ( 4 / 9 )
P ( B ) = ( 5 / 9 )
The probability will be calculated as:-
P( A:B ) =
P( A:B ) =
P( A:B ) = 4 / 9
Therefore the correct answer is option B which is P ( A|B) will be ( 4 / 9 ).
