6.6. A bin of 5 transistors is known to contain 2 thatare defective. The transistors are to be tested, oneat a time, until the defective ones are identified.Denote by N₁ the number of tests made until thefirst defective is identified and by N₂ the number ofadditional tests until the second defective is identi-fied. Find the joint probability mass function of N₁and N₂.
