N = 20, the number of questions p = 1/5 = 0.2, the probability of making a correct guess q = 1 - p = 0.8, the probability of making an incorrect guess. Expected success = 60% or 6 of 10.
From the binomial distribution, P(6 of 10) = ₁₀C₆ p⁶q⁴ = 210*0.2⁶*0.8⁴ = 0.0055
Yes your going to get biased opinions and they would all say yes because they play basketball in the gym so obviously they want good things so they want it to be remodeled
