Joan has a credit card that uses the previous balance method. The opening balance of one of her 30-day billing cycles was $6390,

but that was her balance for only the first 3 days of the billing cycle, because she then paid off her entire balance and didn't make any new purchases. If her credit card's APR is 17%, which of these expressions could be used to calculate the amount Joan was charged in interest for the billing cycle?

For the month of November in a certain​ city, 88​% of the days are cloudy. Also in the month of November in the same​ city, 54​%
Gnoma [55]

Answer:

There is a 61.36% probability that a randomly selected day in November will be foggy if it is cloudy.

Step-by-step explanation:

We have these following probabilities:

An 88% probability that the day is cloudy.

An 54% probability that the day is both foggy and cloudy.

What is the probability that a randomly selected day in November will be foggy if it is cloudy​?

This is the percentage of days that are cloudy and foggy divided by those that are cloudy. So:

P = \frac{0.54}{0.88} = 0.6136

There is a 61.36% probability that a randomly selected day in November will be foggy if it is cloudy.
