answer is 250 which is D Because 250 of 24%=60, so subtract 60 from 250 it will give you 190
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
Answer: 0.0055
Answer:
select a b and c
Step-by-step explanation:
they are all false
D. 80
If you expand the entirety of the polynomial, you get the following:
32x^5+80x^4y+80x^3y^2+40x^2y^3+10xy^4+y^5
Answer:
7/12
Step-by-step explanation:
