Answer: 1. 200, 2. 300
Step-by-step explanation:
40 * 10/2 = 400/2 = 200
or this way:
40 = 20%
40/2 = 20
20 = 10%
20 * 10 = 200
——————————————
90 * 10/3 = 900/3 = 300
or this way:
90 = 30%
90/3 = 30
30 = 10%
30 * 10 = 300

Answer:
2e⁻² ≈ 0.271
Step-by-step explanation:
This is actually a Poisson distribution. The probability is:
P(x; μ) = e^(-μ) (μˣ) / x!
P(2; 2) = e⁻² (2²) / 2!
P(2; 2) = 2e⁻²
P(2; 2) ≈ 0.271
