Step-by-step explanation:
You have to go through your x-axis and up or down you y-axis and then determine if the end point are on the right plot form
Using the principle of binomial probability, the probability of having exactly two black cards is 0.3125
- <em>Probability</em><em> </em><em>of</em><em> </em><em>having</em><em> </em><em>a</em><em> </em><em>black</em><em> </em><em>card</em><em> </em><em>=</em><em> </em><em>26</em><em>/</em><em>52</em><em> </em><em>=</em><em> </em><em>1</em><em>/</em><em>2</em><em> </em>
<u>Using the binomial probability relation</u> :
- P(x = x) = nCx * p^x * q^(n-x)
- <em>p</em><em> </em><em>=</em><em> </em><em>probability</em><em> </em><em>of</em><em> </em><em>success</em><em> </em><em>=</em><em> </em><em>1</em><em>/</em><em>2</em><em> </em><em>=</em><em> </em><em>0</em><em>.</em><em>5</em>
- <em>Number of</em><em> </em><em>picks</em><em>,</em><em> </em><em>n</em><em> </em><em>=</em><em> </em><em>5</em>
- <em>q</em><em> </em><em>=</em><em> </em><em>1</em><em> </em><em>-</em><em> </em><em>p</em><em> </em><em>=</em><em> </em><em>0.5</em><em> </em>
- <em>x</em><em> </em><em>=</em><em> </em><em>2</em><em> </em>
Hence,
P(x = 2) = 5C2 × 0.5² × 0.5³
P(x = 2) = 10 × 0.25 × 0.125
P(x = 2) = 0.3125
Hence. Probability of having exactly 2 black cards is 0.3125

The numbers 35, 2, 7, 33, 25, 70, 75, 40, 42, 12, 15, 7, 44, 20, 25, 3, 65, and 62 are all whole numbers.
- All natural numbers and 0 are considered whole numbers. They are real numbers without fractions, decimals, or negative integers.
- Rounding a number implies simplifying it while retaining its value close to what it was. The end output is less precise but more usable.
- In a given base, a round number is an integer that ends with one or more "0s." So, 590 is more rounded than 592 but less rounded than 600. A round number is frequently understood in both technical and casual language to stand for a value or values close to the nominal value represented.
