Answer:
4/11
Step-by-step explanation:
Add them together
Answer:
2( 2x - y ) -4( x - y ) +3y
4x - 2y - 4x + 4y + 3y
-2y + 4y + 3y
-2y +7y
5y
8 because 2 3 5 7 11 13 17 19
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:
12 years
Step-by-step explanation:
