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:
tooth A
Step-by-step explanation:
0.23 = 0.230
0.230 > 0.195
100/298 = .3355704698 but the answer in a fraction in simplest form is 50/149
Radius 12 units, area = π(12)² = 452.16 unit²
Diameter 16.8 units, area = π(8.4)² = 221.5584 unit²
Radius 3.4 units, area = π(3.4)² = 36.2984 units²
Diameter 10 units, area = π(5)² = 78.5 units²
Answer:
4
Step-by-step explanation:
Looking at the stem and leaf plot, we have 4 zoos that have less than 18 sloths, with one zoo having 3, one having 16, and two having 17.
