Hello there! I can help you! We are loooking for the value of x in this problem. We will solve for it by adding 4 1/6 to both sides of the equation, because a negative number plus a positive number cancels out. -4 1/6 + 4 1/6 cancels out. 9 1/3 (9 2/6) + 4 1/6 is 13 3/6 or 13 ½ in simplest form. x doesn't need to be divided, so we are finished. There. x = 13 ½. The answer is C.

Using conversions between odds and probabilities, we have that:

1. A) 4:21

2. 0.952 probability that a bag of flour passes inspection.

3. C) 1:39

4. 41:59.

5. 14:11

A probability is the number of desired outcomes divided by the number of total outcomes.

An odd is given by a:b, in which a is the number of successes and b is the number of failures.

Item 1:

Probability of 0.16, thus, for 100 trials, 16 successes and 84 failures, and the odd is:

16:84, which, simplifying by 4, is 4:21.

Item 2:

Odd of 20:1 means that 20 + 1 = 21 trials, there are 20 successes, thus, the probability is:

$p = \frac{20}{21} = 0.952$

0.952 probability that a bag of flour passes inspection.

Item 3:

Probability of 0.025, thus, for 100 trials, 2.5 successes and 97.5 failures, and the odd is:

2.5:97.5, which, simplifying by 2.5, is 1:39.

Item 4:

59% probability that he will take the longest trail, thus 100 - 59 = 41% probability of him not tanking the longest trail, thus, the odds against him taking the longest trail is 41:59.

Item 5:
