In a recent year, the ACT scores for high school students with a 3.50 to 4.00 grade point average were normally distributed, with a mean of 24.2 and a standard deviation of 4.3.  A student with a 3.50 to 4.00 grade point average who took the ACT during this time is randomly selected.

1. Find the probability to three significant figures that the student's ACT score is less than 17.  {#1}
   
   
2. Find the probability to three significant figures that the student's ACT score is between 20 and 29.  {#2}
   
   
3. Find the probability to three significant figures that the student's ACT score is more than 32.  {#3}
