Answer:
I deserve brainliest just as all good boys deserves fudgeeeeee
Step-by-step explanation:
v^2 = 25/81
v= the square root of 25/81 = 5/9
since that isn't a choise, don't simplify.
D works too because negative x negative = positive
CCCCCCC
3 to the second power = 3^2
3^2 = 3 x 3
3 x 3 = 9
9 is your answer
hope this helps
Answer: it would be t=13/4
In a pack of 52 cards, there are 26 black cards (13 spade and 13 club), and 26 red cards (13 heart and 13 diamond).
Now, the probability of selecting 1st card from 52 cards: 1;
<span>Remaining cards of same colors = 25;
And, Total remaining cards = 51;
</span>
<span>So, the probability of selecting 2nd card of same color = (1 x 25) / 51
= </span>25/51
An Alternate Method:
The probability of getting two red cards is 26/52 x 25/51
= 1/2 x 25/51
= 25/102.
Since the number of black cards is the same as the number of reds, the probability of selecting two black cards is also 25/102.
<span>So, the probability of selecting two cards of the same color (either both red or both black) is 25/102 + 25/102 = 25/51.
</span>
By using PnC:
Total ways = 52C2
Selecting both Red cards = 26C2
Selecting both Black cards = 26C2
<span>
Thus, Probability = (2 x 26C2)/52C2
= 25/51
</span>
∴ The <span>probability of drawing 2 cards of the same suite is 25/51
