3 equal parts means that the probability of spinning any one part is 1/3. So the probability of getting 1 the first time is 1/3, and the probability of getting 1 the second time is still 1/3. Multiply: $\"%281%2F3%29%2A%281%2F3%29=1%2F9\"$ . The probability is 1/9.\r

\n" ); document.write( "3,2
\n" ); document.write( "3,3\r
\n" ); document.write( "\n" ); document.write( "There were 9 possibilities, and only 1 of them had a 1 both times. Thus, the probability is 1/9. \n" ); document.write( "
