Answer:
It is the fourth option, D.
Answer:
(x⁻¹)(x⁻⁵) = x⁻⁶
Step-by-step explanation:
When multiplying number with the same base, you add up their exponent.
(x⁻¹)(x⁻⁵) =
= x⁽⁻¹⁾ ⁺ ⁽⁻⁵⁾
= x⁻⁶
you can also write x⁻⁶ as 1/x⁶. The negative sign in the exponent just flip the numerator and denominator with each others.
This is found using the binomial distribution with P(H) = 1/2 and P(T) = 1/2 n = 15 and r = 10
= nCr(0.5)^(15-10)(0.5)^10
= 15C10 * 0.5^15 = 0.0916 or 9.16%
