Answer:
a) 0.8333
b) 0.75
c) 0.8181 or 0.9090
Step-by-step explanation:
a)
The probability the visitor selects an authentic painting is
10/12 = 0.8333
b)
Since the opinion of the expert does not depend on your choice, the events are <em>independent</em>, so the probability that the expert says is authentic and it really is, is
0.8333*0.9 = 0.75
c)
If the expert decides the painting is a copy and it is not, then there are 11 paintings of which 9 are authentic, so the probability the visitor selects a new original painting is
9/11= 0.8181
If the expert decides the painting is a copy and it is, then there are 11 paintings of which 10 are authentic, so the probability the visitor selects a new original painting is
10/11= 0.9090

Answer:
<u>David will have the most cookies and he will have two cookies more than Jake</u>
Step-by-step explanation:
1. Let's calculate how many cookies will David cut with his cutter, this way:
Number of cookies = Rolls of cookie dough/Size of the segment
Replacing with the values we know:
Number of cookies = 2/(1/8)
Number of cookies = 16
2. Let's calculate how many cookies will Jake cut with his cutter, this way:
Number of cookies = Rolls of cookie dough/Size of the segment
Replacing with the values we know:
Number of cookies = 2/(1/7)
Number of cookies = 14
<u>David will have the most cookies and he will have two cookies more than Jake</u>
white= 22/4
rye= 11/4
22-11=11
11/4= 2 3/4 more cups of white flour then rye
