We are drawing two cards without replacement from a standard 52-card deck. find the probability that we draw at least one red c

alina1380 [7]

The probability of drawing only one red card in two draws without replacement is given by:
$P(1\ red)=\frac{26C1\times26C1}{52C2}=0.51$
The probability of drawing two red cards in two draws without replacement isgiven by:
$P(2\ red)=\frac{26C2\times26C0}{52C2}=0.245$
The events 'draw one red card' and 'draw two red cards' are mutually exclusive. Therefore the probability of drawing at least one red card is 0.51 + 0.245 = 0.755.

Answer:

<h2>Area = 90 cm²</h2><h2>Perimeter = 53 cm</h2>

Step-by-step explanation:

area and perimeter of the given diagram

<u>area = 1/2 * base * height</u>

where base = 15 cm

height = 12 cm

plugin values into the formula

area = 1/2 * 15 * 12

area = 90 cm²

<u>Perimeter = add up all sides (AB + AC + BC)</u>

where side BC = √(5² + 12²)

BC = 13 cm

Perimeter = 25cm + 15 cm + 13 cm

Perimeter = 53 cm
