Question

Dandelions are studied for their effects on crop production and lawn growth. In one region, the mean number of dandelions per square meter was found to be 8.8. Find the probability of no dandelions in an area of 1 m2. P(X = 0) = Find the probability of at least one dandelion in an area of 1 m2. P(at least one) = Find the probability of at most two dandelions in an area of 1 m2. P(X < 2) = Question Help: Message instructor Submit Question

Need help with how to input these onto TI-83 plus. Need help with learning how to use the functions to compute these equations on my calculator.

Answer 1

let X ~ Poisson (8.8) mean 8.b PlX = k) = d k kl e PlX= o) - 8.8 (8.2) ol 8.8 - 0.00015 2 Plx>1)=1. PlX < 1) = 1- Plx=o) = 1-0.00015 = 0.99985 ③ P( x42) = p (=o) + P(x=1) + P(X=2) 8.8 8 3 2 P( X=2)= é 8. 8 2 P(X=1) = 0.00/33 21 - 8.8 0.005844 838.72 x e P(x<2) = 0.00015 + 8 99985 +0.00584 0.00133 Please like = 0.00732
