Case:
87 Sportalkers practice sports as shown in the table below:
Group | Football | Basketball | Tennis | Swimming |
1 | 4 | 6 | 4 | 10 |
2 | 8 | 6 | 3 | 7 |
3 | 5 | 4 | 2 | 10 |
4 | 3 | 4 | 1 | 10 |
sum | 20 | 20 | 10 | 37 |
It's known that:
- None sporstalker practices more than one sport
- Half the members in each sport are men.
If we choose one of the sportalkers at random, ¿What is the probability of choosing a woman who plays basketball?
Solution:
P(BW) = BW/ 2 =10 /N
P(Bw)= 10/87 = 11.49%
Answer:
The probability of choosing at randomly a woman who plays basketball among the 87 sportalkers is 11.49%.
