MHB Probability of Even # or Mult. of 3 from 1-10

Click For Summary
The discussion focuses on calculating the probability of selecting an even number or a multiple of 3 from the numbers 1 to 10. Even numbers in this range are 2, 4, 6, 8, and 10, while the multiples of 3 are 3, 6, and 9. The overlap between even numbers and multiples of 3 includes the number 6. Participants clarify that "multiply of 3" refers to multiples of 3, specifically 3, 6, and 9. The final probability is derived from the total favorable outcomes versus the total possible outcomes.

They mean the multiples of 3, which are 3, 6, and 9.
 
I have been insisting to my statistics students that for probabilities, the rule is the number of significant figures is the number of digits past the leading zeros or leading nines. For example to give 4 significant figures for a probability: 0.000001234 and 0.99999991234 are the correct number of decimal places. That way the complementary probability can also be given to the same significant figures ( 0.999998766 and 0.00000008766 respectively). More generally if you have a value that...
