5. (22+11.5x)+(54+23.4x).

=(22+54)+(11.5x+23.4x).

=76+34.9x.

=34.9x+76.

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 <u>number of desired outcomes divided by the number of total outcomes</u>.
  • An odd is given by a:b, in which <u>a is the number of successes and b is the number of failures</u>.

Item 1:

  • Probability of 0.16, thus, for 100 trials, <u>16 successes and 84 failures</u>, and the odd is:

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

Item 2:

  • Odd of 20:1 means that 20 + 1 = <u>21 trials, there are 20 successes</u>, 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, <u>2.5 successes and 97.5 failures</u>, 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 <u>not tanking the longest trail</u>, thus, the odds against him taking the longest trail is 41:59.

Item 5:

  • Probability of 0.56, thus, for 100 trials, <u>56 successes and 44 failures</u>, and the odd is:

56:44, which, simplifying by 4, is 14:11.
