Answer:
the probability that a student chosen at random plays football or cricket or both =
Step-by-step explanation:
i) 8 students play football and cricket
ii) 4 students do not play football or cricket
iii) total of 14 students play football.
iv) therefore the number of students who play only football is = 14 - 8 = 6
v) total of 20 students play cricket.
vi) therefore the number of students who play only cricket is = 20 - 8 = 12
vii) therefore the total number of students = 8 + 4 + 6 + 12 = 30
viii) the probability a student chosen at random plays football =
ix) the probability a student chosen at random plays cricket =
x) the probability a student chosen at random plays both football and cricket =
xi) therefore the probability that a student chosen at random plays football or cricket or both =
