Answer: There is probability of 96.4% that a day in March will be foggy if it is a cloudy.
Step-by-step explanation:
Since we have given that
Probability of the days in March are cloudy = 57%
Probability of the cloudy days in March are foggy = 55%
Let A be the event of cloudy days in March.
Let B be the event of foggy days in March.
So, here,
P(A) = 0.57
P(A∩B) = 0.55
We need to find the probability that days are foggy given that it is cloudy.
We would use "Conditional probability":
Hence, There is probability of 96.4% that a day in March will be foggy if it is a cloudy.
Answer:
8+x/2 = 12
=> x/2 = 12 - 8
=> x/2 = 4
=> x = 4 * 2
=> x = 8

7-X. Decrease is subtraction.
Let x = Edna's age
then it follows that (x + 1) is Ellie's age and (x + 2) is Elsa's age
We can now write and equation for the sum of their ages equal to 108:
x + (x + 1) + (x +2) = 108 simplify the left side
3x + 3 = 108 subtract 3 from both sides
3x = 105 divide both sides by 3
x = 35
Edna is 35, Ellie is 36, and Elsa is 37
