Problem 1.2 (e),(f)These sums are not convergent so strictly speaking they do not make sense.
Problem 1.14 The solution for this problem is inconsistent with the question. To match the solution, this question should ask for the sum of the first 9, 19, 29 . . . numbers.
Problem 1.21
and Figure 1.4
The question should read "A triangle is inscribed in a circle of radius r=1 . . . ". Also, the letter F in Figure 1.4 should be a B.

Chapter 2The problems are all mislabelled 1.# instead of 2.#
Figure 2.6Instead of "quadratic", it should say "cubic". (This Figure is labeled 1.6 but should be 2.6.)
Problem 2.5There is only one intersection point so the area "between" intersection points is technically zero. Assume that the question asked for the area between the functions from x=0 to the intersection point.

Problem 4.9Assume the Nile is infinitely long so that x can range from 0 to infinity.
Problem 4.17It should say 0 <= t <= 30 rather than 0 < t < 30.

Problem 5.9The followed modifications to this question might make it a bit more clear:
"Suppose a lake has a depth of 40 meters at its deepest point and . . . z is the height in meters above the lowest point of the bowl."
The volume of the lake is the volume above the curve z=x2/10 and below z=40.

Problems 8.3, 8.7, 8.11, and 8.13(e)Assume that the coins are fair.
Problem 8.13The question should refer to "the probability distribution", and not "the probability density distribution".
Problem 8.14"A biased coin", not "A bias coin".
Problem 8.15 "Select a sample of 3 with replacement" means consider the following experiment: three times you randomly choose one of the 7 items in the shipment (with equal probabilities for each of the 7 items), test whether it's good or defective, and then put it back (so it's possible that the same item could be chosen more than once). The question asks what is the probability that the result of this experiment is that you choose a good item twice and a defective item once.

12.8For (a), sketch the two on the same axis and make it clear, for all values of x, which curve lies above the other and if/where they switch. For (c), "bigger and bigger" means not just "increasing" but "increasing without bound".
