Answer:
Expected value E = $0.45
Step-by-step explanation:
Expected value E = P×w - P'×l
Where;
P = probability of making the next 2 throw.
P = 223/406 × 223/406 = 0.3017
P' = probability of not making a throw.
P' = 1 - P = 1 - 0.3017
P' = 0.6983
w = expected win = $20
l = Expected loss = $8
Substituting the values;
E = 0.3017 × $20 - 0.6983 × $8
E = $0.4476
Expected value E = $0.45

Step-by-step explanation:
Its c because 11/10 gives you a whole number
Answer:
1/168
Step-by-step explanation:
First, solve for the numerator.
-5/7÷30
-5/7÷30/1
(use keep, change flip)
-5/7x1/30=-5/210
-5/210=-1/42
Now use keep change flip again
-1/42÷-4/1
-1/42*-1/4=1/168
