Answer:
what is the question and the choices and ill answer this
Step-by-step explanation:
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: b would actually be the closest but the exact answer is 145.2
Answer:
Step-by-step explanation:
Your gonna subtract the cost of the pair earrings from the total. 260-15=245, then you will divide 245 by 7. 245/7=35. So each bracelet cost's 35 each.
