Consider the chance of rolling two dice.
\n" ); document.write( "a) What is the probability that you get either two ones?
\n" ); document.write( "Comment: \"either two ones\" or WHAT?
\n" ); document.write( "b) What is the probability that a perfect square would be shown on two dice?
\n" ); document.write( "If you are summing the faces you could get
\n" ); document.write( "4: (1,3) (3,1)(2,2) = 3/36
\n" ); document.write( "9: (3,6)(6,3)(4,5),(5,4)=4/36
\n" ); document.write( "P(sum is perfect square)= 7/36\r
\n" ); document.write( "\n" ); document.write( "c)What is the probability that a prime number is equal to the total number of points on the two dice.
\n" ); document.write( "2: (1,1) = 1/36
\n" ); document.write( "3: (1,2)(2,1)=2/36
\n" ); document.write( "5: (1,4)(4,1)(2,3)(3,2)=4/36
\n" ); document.write( "7: (1,6)(6,1)(2,5)(5,2)(3,4)(4,3)=6/36
\n" ); document.write( "11: (5,6)(6,5)=2/36
\n" ); document.write( "P(prime sum)=15/36
\n" ); document.write( "-----------------
\n" ); document.write( "d)What is the probability that a ten would not appear on the two dice?
\n" ); document.write( "P(no ten)= 1-P(10)
\n" ); document.write( "=1-5/36=31/36
\n" ); document.write( "----------
