A standard deck of cards has 52 cards divided into 4 suits, each of which has 13 cards. Two of the suits ( and , called `hearts'
motikmotik

Answer:

The probability that the first two cards drawn from the deck are both red is 24.51%

Step-by-step explanation:

A standard deck of cards has 52 cards. There are 4 of each card (4 Aces, 4 Kings, 4 Queens, etc.) . There are 4 suits (Clubs, Hearts, Diamonds, and Spades) with each suit being 13 cards .  Two of the suits (hearts and diamonds) are red, the other two (spades and clubs) are black.

P(first two cards drawn from the deck are both red)= P(First card is red) ∙× P(Second card is red)

Since two suits of the card is red (i.e hearts and diamond) and each suit consist of 13 cards, the total number of red cad = 13 + 13 = 26

P(First card is red) = number of red card / total number of cards = 26 / 52

When the first card is drawn without replacement i.e the card is not put back into the deck, the total number of card reduces to 51 and the number of red card reduces to 25.

Therefore, P(Second card is red) = 25 / 51

P(first two cards drawn from the deck are both red)= P(First card is red) ∙× P(Second card is red) = (26 / 52) × (25 / 51) = 0.2451 = 24.51%

The probability that the first two cards drawn from the deck are both red is 24.51%

Can someone plz help me with this plzzzzz
Vladimir79 [104]

Answer:

D. m = \sqrt{3}, n = 1

Step-by-step explanation:

The triangle given is a 30-60-90 triangle. This means that the longer side of the leg is x\sqrt{3} (m), the shorter side of the leg is x (n), and the hypotenuse is 2x.

The hypotenuse is already given as 2, and since the hypotenuse is 2x, to find the shorter side (n), just divide by 2, giving you n = 1.

Now onto the longer side (m); it's represented by x\sqrt{3}, and since x is just 1, all you do is put x in front of \sqrt{3}.

But in this case, x is just 1, so it's like "imaginary," and doesn't need to be written out.
