Introduce the following notations of events:
A "The person has the disease"
B "The test is positive", C "the test is erroneous"
Our formula will be then:
So the probability we are looking for is 0.19
The possible combinations are:
1,9
2,8
3,7
4,6
9,1
8,2
7,3
6,4
Total straws: 9
Probability of first being 1: 1/9
Probability of second being 9: 1/8
Probability of both: 1/9 x 1/8 = 1/72
This will be multiplied by 8 as there are 8 possible combinations:
8 x 1/72
= 8/72
= 1/9

Answer:
(b) $1.15
Step-by-step explanation:
The expected value is the sum of products of payoff and probability:
$0×0.15 +0.50×0.5 +1.0×0.2 +2.0×0.1 +10×0.05
= $0 +0.25 +0.20 +0.20 +0.50
= $1.15 . . . . expected value of the scratch ticket
