What is the probability that a coin will be flipped 4 times and the result will be HTHT?

The number of typographical errors in a document follows a Poisson distribution with a mean of 3 errors per page. Let X represen

n200080 [17]

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
