Given:
no. of visitors with no costume purchased = 92
no. of visitors with 1 costume purchased = 20
no. of visitors with more than costume purchased = 8
Total no. of visitors = 92+20+8 = 120
to find: probabality of next visitors who will purchase 1 costume = ?
Solution:
total no. of visitors
S = 120
n(S) = 120
Let A be the event where visitors purchase only 1 costume
A ={20}
n(A) = 20
P(A) = n(A)/n(S)
P(A) = 20/120 = 1/6
P(A) = 1/6
Ans:Probability of next person who will purchase 1 costume is 1/6
