Answer:
0.114,0.5263
Step-by-step explanation:
Given that a firm buys components from two suppliers:
A : 60% Defective 9%
B:40% Defective 15%
a) the probability that the next component the firm buys is defective
=prob purchased from A and defective + prob purchased from B and defective
= 
b) the probability that the component that the firm buys is from supplier B if we know that it is defective
=Prob from B and defective/Prob defective
= 
First add up the numbers.
27.2+13.5+42.1+37.9+25=145.7
Now divide it by 5
29.14 or 29.1 rounded is the answer
<span>$2.35
Working
Let p represent the cost of pretzels and L the cost of a lemonade.
From the second paragraph,
2p+ L= 5.75
From the equation above, the cost of a pretzel p can be expressed as:
2p= 5.75 - L
p= 5.75/2 - l/2
The cost of two lemonades exceeds that of a pretzel by 0.25:
2 L= 5.75/2 -L/2+0.25
Solving this gives:
L=1.05
Then replace the value of L in </span><span>p= 5.75/2 - L/2
</span><span>This gives the value of a pretzel.
