Question

the following probability model shows the distribution of injuries of youth baseball players, ages 5 - 14, according to researchers at sportmedbc. complete parts (a) through (d)

c. yes, the probability of all events in the table is greater than 0 and less than 1, and the sum of the probabilities of all outcomes equals 1.

d. yes, the probability of all events in the table is greater than or equal to 0 and less than or equal to 1, and the sum of the probabilities of all outcomes equals 1.

(b) what is the probability that a randomly selected baseball injury to a 5 - 14 - year - old is to the face or wrist? interpret this probability.

p(face or wrist) = 0.384 (round to three decimal places as needed.)

interpret this probability. select the correct choice and fill in the answer box to complete your choice.

a. if 1000 baseball injuries to 5 - 14 - year - olds were randomly selected, one would expect exactly of them to have happened to the face or wrist.

b. if 1000 baseball injuries to 5 - 14 - year - olds were randomly selected, one would expect about of them to have happened to the face or wrist.

Explanation:

Step1: Calculate the expected number

The probability \(P(\text{face or wrist}) = 0.384\). To find the expected number when \(n = 1000\), we use the formula \(E=n\times P\).

$$E = 1000\times0.384$$

Step2: Perform the multiplication

$$1000\times0.384=384$$

Answer:

B. If 1000 baseball injuries to 5 - 14 - year - olds were randomly selected, one would expect about \(384\) of them to have happened to the face or wrist.
