(a)  The probability to have first number even is  5%2F10 = 1%2F2  (five possible favorable outcomes among 10 possible outcomes).


     The probability to have second number even is  5%2F10 = 1%2F2,  the same value, again.



     The probability to have both first and second numbers even is the product


          P = %281%2F2%29%2A%281%2F2%29 = 1%2F4.    ANSWER
