Answer:
82.6%
Step-by-step explanation:
Conditional probability is defined as:
P(A|B) = P(A∩B) / P(B)
where P(A|B) is the probability of A on the condition of B, P(A∩B) is the probability of both A and B, and P(B) is the probability of B.
Here, we want P(P|K), so:
P(P|K) = P(P∩K) / P(K)
P(P|K) = 0.019 / 0.023
P(P|K) = 0.826

Answer: $200
Explanation:
The employee pays $172.50 and he got 25% employee discount.
If the cost is $100, he pays $(100 - 25) = $75.
So, employee pays =
100
75
⋅
172.50
= $230.00.
Again, price was increased by 15% last year. So whose cost is $100
is sold by $(100+15) = $115.
When sell price is $115, then cost price is $100. Then,
when sell price is $230, then cost price is
100
115
⋅
230
= $200.
