Step-by-step explanation:
Answer: The required probability that a randomly selected day in November will be snowy if it is cloudy is 86.79%.
Step-by-step explanation: Given that for the month of November in a certain city, 53% of the days are cloudy. Also in the month of November in the same city, 46% of the days are cloudy and snowy.
We are to find the probability that a randomly selected day in November will be snowy if it is cloudy.
Let A denote the event that the day is cloudy and B denote the event that the day is snowy.
Then, according to the given information, we have
Now, we need to find the conditional probability of event B given that the event A has already happened.
That is, P(B/A).
We know that
Thus, the required probability that a randomly selected day in November will be snowy if it is cloudy is 87.79%.

The perimeter of the new rectangular piece of glass is 80m.
<h3>
What is the perimeter of a rectangle?</h3>
- The sum of all sides of a rectangle is the perimeter of the rectangle.
- A rectangle has two equal lengths and two equal widths.
- Therefore, the perimeter 'P' of a rectangle is the sum of two equal lengths and two equal widths.
- That is, 'P=2l+2w' where 'l' is the length and 'w' is the width of the rectangle.
Here, a rectangular piece of glass has a perimeter of 20 meters.
As we know the perimeter P of a rectangle is given by the formula,
P = 2l+2w...(1)
Therefore,
20 = 2l + 2w
20 = 2(l + w)
20/2 = l + w
10 = l + w ....(2)
Now, both the length and width of the rectangle are multiplied by 4,
That is,
The new length of the rectangle is, l = 4l
The new width of the rectangle is, w = 4w
Therefore by substituting this in the equation(1) we get,
P = 2(4l) + 2(4w)
P = 8l + 8w
P = 8(l+w)....(3)
Substitute equation (2) in (3),
That is,
P = 8*10
P = 80m
