Answer:
probability of x is 0.22 correct to two decimal places
Step-by-step explanation:
step 1. use the poisson formula given as
p(x) = (λˣe∧-λ) ÷x! where λ is the mean and it called lambda,λ = 3, e is mathematical constant and it approximately = 2.7183, x is the chosen value which is equal to 2, Λ is raise to power, ! is factorial sign
p(x=2) =( 3² x 2.7183⁻³) ÷ 2! = 0.22
Answer:
63%
225 buyers
Step-by-step explanation:
To find the percent take the number that liked it over the total
376/600
Change to decimal form
