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
<span>Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. the absolute value of a number is negative.</span>
It's an irrational number which means the number never ends and has no pattern in its decimal. So you would round it:
9/6.5= 1.384615384615385
but the answer would be 1.384
Answer:
y = - 35
Step-by-step explanation:
Expressing as a fraction , that is
= 5 ( multiply both sides by - 7 to clear the fraction )
