• Assignment 2 (#14, 18, 20, 24 from 5.2 and #22 from 5.3 — due at the beginning of lab session on March 4th or 5th)
• Assignment 3 (#22, 36, 46 from 6.1 — due at the beginning of lecture on March 9th — show necessary work by hand without a calculator)
• Assignment 4 (#14, 16 from 6.2 — due at the beginning lecture on March 11th)
• Assignment 5 (#16a, 16b, 22, 24, 28 from section 2.1. For #22 you need to read the part just before problems 21-22 but you do not need to include a sketch. — due at the beginning of lab session on April 1st or 2nd)
• Assignment 6 (#12, 24, 30 from section 6.3. — due at the beginning of your lab session on April 8th or 9th) — For #12 you can use any method (you do not need to use Decimal Squares). For #24 the final answer must be written in scientific notation. For example if your answer is 5200000, then write your result as 5.2 × 10⁶ instead of 5.2E6 that a calculator might display.

• Assignment 8 (#10, 14, 16, 20 from section 8.1 — due at the beginning your lab session on April 15th or 16th. For #14 I recommend that you try the experiment with marbles or slips of colored paper 50-100 times. Does the experimental data support your answer for the probabilities found? If not, are you sure you calculated the probabilities correctly?
