Determine if the events A and B are independent. Show all steps.

zmey [24]

Answer:

$P(A U B ) = \frac{13}{25}$

Step-by-step explanation:

STEP:-1

Given that events A and B are independent then

P(A ∩B ) = P(A) P(B)

Given that P(A) = 2/5 and P(B) = 1/5

STEP:- 2

P(A ∩B ) = P(A) P(B)

$P(A U B) = P(A) +P(B) - P(A n B )$

$P(A U B ) = P(A) +P(B) - P(A) P(B)$

Step(iii):-

$P(A U B ) = \frac{2}{5} +\frac{1}{5} - \frac{2}{5} X \frac{1}{5}$

$P(A U B ) = \frac{3}{5} - \frac{2}{5} X \frac{1}{5}$

$P(A U B ) = \frac{3}{5} - \frac{2}{25}$

$P(A U B ) = \frac{15-2}{25} = \frac{13}{25}$

If the lateral area of a right rectangular prism is 384 cm^2, its length twice its width, and its height is twice its length, fi

Katen [24]

Width = w
Length = 2w
Height = 4w
$w \times 2w = 384 \\ {2w}^{2} = 384 \\ {w}^{2} = 192 \\ w = 13.86cm$
Width = 13.86cm

Answer:

24 ft²

Step-by-step explanation:

The formula to solve for area of a triangle is: $\frac{1}{2} bh$ . First multiply the base x height: 12 x 4 = 48. Now multiply by 1/2: 48 x 1/2 = 24. Your answer is 24 ft².

Hope it helps and is correct!
