L = w + 7
W = w
A = L * W
120 = w(w+7)
120 = w^2 + 7w
Subtract 120 from both sides.
w^2 + 7w - 120 = 0
Factor
(w + 15)(w - 8) = 0
Set each factor equal to zero.
w = -15, w= 8
Cannot be -15 so w = 8
Length = 15
Width = 8

Problem 1: Given the following probabilities P(Ac) = 0.45, P(B) = 0.34, and P(B|A) = 0.23. Find the following probabilities:
-BARSIC- [3]

Answer:

P(A)=0.55

P(A and B)=P(A∩B)=0.1265

P(A or B)=P(A∪B)=0.7635

P(A|B)=0.3721

Step-by-step explanation:

P(A')=0.45

P(A)=1-0.45=0.55

P(B∩A)=?

P(B|A)=0.23

P(B|A)=(P(A∩B))/P(A)

0.23=(P(A∩B))/0.55

P(A∩B)=0.23×0.55=0.1265

P(A∪B)=P(A)+P(B)-P(A∩B)

=0.55+0.34-0.1265

=0.7635

P(A|B)=[P(A∩B)]/P(B)=0.1265/0.34 ≈0.3721

The probability that a dancer likes ballet is .35. The probability that the dancer likes tap is .45. The probability that the da
Tom [10]

It is given the probability that a dancer like ballet is 0.35

So, P(B) = 0.35

It is given the probability that a dancer like tap is 0.45

So, P(T)= 0.45

The probability that he likes both ballet and tap is 0.30

So, P(B\cap T)=0.30

the probability that the dancer likes ballet if we know she likes tap. This is the case of conditional probability.

So, P(B/T)=\frac{P(B\cap T)}{P(T)}

P(B/T)=\frac{0.30}{0.45}

= 0.666

= 0.67

Therefore, the probability that the dancer likes ballet if we know she likes tap is 0.67.

Option 3 is the correct answer.
