A standard die is rolled six times. What is the probability that the product of all six rolls is odd? Express your answer as a common fraction.

If the product of all 6 rolls is, odd...EVERY roll must be odd, since any even roll - or multiple even rolls -  in the 6  will  result in an even product

 

We have a (1/2)  probability of an odd roll on each roll....so....the probability of  an odd product on  6  rolls  is :

 

(1/2)^6   =  1 / 64
