If two cards are drawn without replacement from a 52 card deck, find the probability that the second card drawn is red, given th

snow_lady [41]

Answer:

The probability that the second card drawn is red, given that the first card was a heart is 0.1225

Step-by-step explanation:

Total cards in a deck = 52

Total red cards = 26

Heart cards = 13

Probability of getting red card = $\frac{13}{52}$

Total remaining card = 51

Remaining red cards = 25

Probability of getting red card in second draw without replacement = $\frac{25}{51}$

So, the probability that the second card drawn is red, given that the first card was a heart = $\frac{13}{52} \times \frac{25}{51} =0.1225$

Hence the probability that the second card drawn is red, given that the first card was a heart is 0.1225

What is the area of the figure abcd

expeople1 [14]

Answer:

66 square inches

Step-by-step explanation:

The area of the figure can be found by adding the area of the rectangle and the triangle together.

The area of a rectangle is found A = l*w. Here l = 10 and w = 6. So the area of the rectangle is 10*6 = 60.

The area of a triangle is found A = 1/2 b*h. Here b = 2 from 12-10 = 2 and h = 6. So the area of the triangle is 1/2 * 2* 6 = 6.

The area together is 60 + 6 = 66 square inches.

I need a check so just want some help

bazaltina [42]

Answer and Step-by-step explanation:

We are told that AB is equal to 3x + 1.

BC is then half of AB, or $\frac{3x+1}{2}$ .

AC is then 4 less than BC, or $(\frac{3x+1}{2} ) - 4$

To find the perimeter, we add all of these together.

3x + 3x/2 + 3x/2 = 6x

1 + 1/2 + (1/2 - 4) = -2

The final answer is 6x - 2.
