Answer:
Therefore the correct answer is A.) 84.88%
Step-by-step explanation:
i) λ = 2
ii) λ for three units = 2
3 = 6
iii) P(x ≥ 4) = 1 - P(x < 4) = 1 - {P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) }
= 1 - {
}
= 1 - (0.0025 + 0.0149 + 0.0446 + 0.0892)
= 0.8488
Therefore the correct answer is A.) 84.88%
Denominator:

so excluded values are x = -1 and x = 1.
Answer D.
Answer:
3 animals
Step-by-step explanation:
- combine like terms
- 6 + 2x = 15 + x
- -6 + x - 6 - x
--------------------------
3x = 9
2. divide both sides by 3
I believe the answer is 1. One is the only number that can go into both 8 and 9.
