Cards are dealt, one at a time, from a standard 52-card deck. a if the first 2 cards are both spades, what is the probability th

ratelena [41]

So we already drew two cards and both of them are spades. So that means there are 50 cards and 11 spades left.

Then third card being spades would be 11 / 50

Now there are 10 spades and 49 cards left.
So the probability for fourth card would be 10 / 49

Fifth card would be 9 / 48.

So the probability of next three cards being spades would be
$\dfrac{11}{50}\cdot\dfrac{10}{49}\cdot\dfrac9{48}=\dfrac{33}{3920}\approx\boxed{0.00842}$

Hope this helps.

How do you solve this equation ( ASAP PLS )

makvit [3.9K]

Solve this by substitution:

Solve 5x - 4y = -13 for x:5x − 4y + 4y = -13 + 4y (Add 4y to both sides)
5x = 4y - 13 (Divide both sides by 5)
5 5

x = 4 y + -13
 5 5
You can use https://www.mathpapa.com/algebra-calculator.html
5x - 4y = -13, 8x +10y = 12 (enter both equations with a comma between them and it will solve for you and show you step by step.

I dont get it?? how do i set it up?? im so... confused?? can i get some helpm

snow_tiger [21]

Well, you need a diagram (see attached).

Since angle S = angle T then

9x -11 = 7x -3 ...... 2x = 8 ........ x = 4

RS = RT = 4

There must be some more information that can't be seen
