Answer:
1.)
P(E) = 0.5
P(A) = 0.2
P(N) = 0.3
Conditional probability ;
0.47
Step-by-step explanation:
Let :
E = Excellent ; A = Average ; N = not up to standard
P(E) = 0.5
P(A) = 0.2
P(N) = 0.3
If Leo shows up ; this type of probability is called a conditional probability. It is the likelihood of an event based on a certain or already satisfied condition.
The probability that Leo is coming :
Leo ; Excellent = 0.7
Leo ; Average = 0.3
Leo; Not up to standard = 0.2
Hence, probability they Leo is coming :
(0.5 * 0.7) + (0.2 * 0.3) + (0.3 * 0.2)
0.35 + 0.06 + 0.06
= 0.47
Answer:

The answer is A in this case
Answer:
Length in feet is equal to
, where P is the perimeter
Step-by-step explanation:
Let the width (W) of the yard be "X"

Then the length(L) of the yard will be


The perimeter of the yard will be equal to the sum of twice the length and width of the yard
Thus,

Substituting the given values in above equation, we get -

Thus, width in terms of perimeter is equal to

Length in feet is equal to
