 Number of green tickets = 3

Number of yellow tickets = 4

Number of blue tickets = 5

Total number of tickets = 3 + 4 + 5 = 12

(i) P (getting a green ticket) = 3/12 = 1/4

(ii) Total Number of green and yellow tickets

= 3 + 4 = 7 tickets

P (getting a green or yellow ticket) = 7/12

(iii) Since, Basket contains green, yellow and blue tickets only.

∴ Number of orange tickets = 0

∴ P (getting an orange ticket) = 0/12 = 0
