Answer:
Step-by-step explanation:
total number of students=21
students play neither sport=6
students who play at least one sport=21-6=15
Let play basketball=X
and play baseball=Y
n(XUY)=n(X)+n(Y)-n(X∩Y)
15=11+6-n(X∩Y)
n(X∩Y)=17-15=2
reqd. probability=2/21
Using it's concept, it is found that there is a 0.625 = 62.5% probability that an individual owns a stock.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, out of 200 graduates, 35 + 90 = 125 of them own stocks, hence:
p = 125/200 = 0.625.
There is a 0.625 = 62.5% probability that an individual owns a stock.
