If You Flip A Coin And Toss A 1-6 Number Cube, What Is The Probability Of Choosing A Prime Number And Tails.

I believe it is 1/3 or 33.3%. You take the probability of getting tails, which would be 1/2 or 50%, and multiply that by 4/6 or 2/3 or 66%, the probability of getting a prime number. It would be 4 out of six because 1,2,3 and 5 are prime out of 1 2 3 4 5 and 6. So, 2/3*1/2=2/6 or 1/3.

I concur with Capuchin.
of {1 2 3 4 5 6} {2 3 5} are prime

Yes I forgot about that 1 is not prime, but was it really necessary for you to take another blow to my profile, Capuchin?
