✔ 最佳答案
P(x = 8)
= ₁₇C₈ (0.6)⁸ (1 - 0.6)¹⁷⁻⁸
= (17!/8!9!) × (0.6)⁸ × (0.4)⁹
= 0.1070

Apply the formula you saw; apply the probability mass function. See
https://en.wikipedia.org/wiki/Binomial_distribution#Probability_mass_function

nCk * p^k * (1-p)^(n-k).

What is your n?  your p? your k?
Compute. Done!



Hopefully no one will spoil you the answer. That would be very irresponsible of them.
