sveticcg [70]

Answer:

The required probability is 0.4098.

Step-by-step explanation:

Consider the provided information.

According to conditional probability that A occurs , given B has occurred.

P(A|B)=\frac{P(A\cap B)}{P(B)}

Assume that the car lot contains 40 percent BMWs, 25 percent Volvos, and 35 percent Jaguars.

Pr(BMWs)=0.40

Pr(Volvos)=0.25

Pr(Jaguars)=0.35

Of the BMWs, 90 percent have navigation systems, 30 percent of the Volvos have navigation systems, and 50 percent of the Jaguars have navigation systems.

Pr(Navigation | BMWs)=0. 90

Pr(Navigation l Volvos)=0.30

Pr(Navigation l Jaguars)=0.50

Total cars with navigation system = 0.40×0.90+0.25×0.30+0.35×0.50

=0.36+0.075+0.175=0.61

Pr(Not Bmw l Navigation system) = \frac{0.25\times0.30+0.35\times0.50}{0.61}\approx0.4098

Hence, the required probability is 0.4098.

solmaris [256]

Answer:

50 cm^2

area of triangle = base * height / 2

5 * 4 = 20/2 = 10

5 * 2 = 10/2 = 5

add them all up
