Answer:
$160 was the price at which glasses were advertised.
Step-by-step explanation:
Nick bought a pair of glasses for 200.
He later saw the same glasses advertised for 20% less than what he originally paid.
We have to find the price of the glasses as per advertisement.
Price of the sunglasses after discount of 20% = Price Nick paid - 20% of price Nick paid
= 200 - 20% of 200
= 200 - 200×
= 200 - 200×0.2
= 200 - 40
= 160
Therefore, the price of the glasses was $160 in the advertisement.

Step-by-step explanation:
Since we have given that
Number of coins = 3
Number of coin has 2 heads = 1
Number of fair coins = 2
Probability of getting one of the coin among 3 =
So, Probability of getting head from fair coin =
Probability of getting head from baised coin = 1
Using "Bayes theorem" we will find the probability that it is the two headed coin is given by
Hence, our required probability is
