Abaseball player was that bat 473 times during a regular season. if he made a hit 31. 5 % of the time he was at bat how many hits did he make during the regular season? round to the nearest whole number if necessary

He made 149 hits during the regular season.

Step-by-step explanation:

Given : A baseball player was that bat 473 times during a regular season.

If the made a hit 31. 5 % of the time .

We can rewrite 31.5% as 0.315.  [ To convert percent into decimal we divide it by 100.]

Now, the number of hits he made during the regular season will be :-

[Rounded to nearest whole number]

Hence, He made 149 hits during the regular season.

The probability that a person with restless leg syndrome has fibromyalgia is 0.1833.

Step-by-step explanation:

Denote the events as follows:

F = a person with fibromyalgia

R = a person having restless leg syndrome

The information provided is as follows:

P (R | F) = 0.33

P (R | F') = 0.03

P (F) = 0.02

Consider the tree diagram attached below.

Compute the probability that a person with restless leg syndrome has fibromyalgia as follows:

Thus, the probability that a person with restless leg syndrome has fibromyalgia is 0.1833.
