True or false? on average, 20% of the emergency room patients at greenwood general hospital lack health insurance. in a random sample of 4 patients, the probability that only one patient will be uninsured is 0.4096.

To solve this, we use the binomial probability equation.

P = [n! / (n – r)! r!] p^r * q^(n – r)

where n is the total number of sample patients = 4, r is the number of uninsured patients = 1, p is probability of being uninsured = 0.20, q is 1 – p = 0.80

Calculating for probability P:

P = [4! / (4 -1)! 1!] 0.20^1 * 0.80^(4 – 1)

P = 0.4096

explanation:

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.
