Probability is:
Explanation of Solution
Given:
Two numbers are randomly selected without replacement from the set
Formula Used:
Where,
Calculation:
Even numbers in the provided set are
It is provided that numbers are drawn without replacement. So, probability of the event that both numbers are drawn even without replacement is:
The probability of the event that both numbers are drawn are even is:
