Assume that a fair six-sided die is rolled 13 times, and the roll is called a success if the result is in {1,2,3,4}. What is the
Deffense [45]

Answer:

The answer to the question is;

The probability that there are exactly 4 successes or exactly 4 failures in the 13 rolls is \frac{715}{8192}.

Step-by-step explanation:

The probability of success = 1/2 =

probability of failure  = 1/2

Since we have 4 success we then have 9 failures and the given probability can be solved as ₁₃C₄ × 1/2ⁿ×1/2¹³⁻ⁿ

Therefore  we have

₁₃C₄ × 1/2⁴×1/2⁹ =  715/8192

That is the probability that there are exactly 4 successes or exactly 4 failures in the 13 rolls = 715/8192.

Aleks04 [339]
Hi there!

a. 8x^2 - 1
(x^2 - 4x + 5) + (7x^2 + 4x - 6)
= x^2 + 7x^2 - 4x + 4x - 1
= 8x^2 - 1

b. 5x^2 + 7x - 7
(7x^2 + 4x - 6) - (2x^2 - 3x + 1)
= 7x^2 + 4x - 6 - 2x^2 + 3x - 1
= 7x^2 - 2x^2 + 4x + 3x - 6 - 1
= 5x^2 + 7x -7

Hope this helps!
