Female students in a certain school in Ghana engage in various sports in the following proportions:
Football- 40%
Basket ball- 20%
Tennis- 15%
Both football and tennis- 10%
Both basketball and tennis- 5%
All three sports- 3%
If a female student is chosen at random from the university,use a Venn diagram to calculate the probability that she plays:
1. At least one of the sports
2. Football only
3. Football or Tennis
@ojiugo,
You are missing "Both football and basketball". I think that is required to compute 1 and 2. Number 3 = Football + Tennis - Football intersect Tennis = 40 + 15 - 10 = 45%
