Right Answer is:
SOLUTION
(1)Total number of outcomes = 5
There is only one queen.
∴ Favourable outcome = 1
Hence, P(getting a queen) = 15
(2)
Total number of outcomes before queen is drawn = 5
Total number of favourable outcomes after queen is drawn and put aside = 4
(a) Favourable outcome = 1
Hence, P (getting an ace) = 14
(b) There is no card as queen.
∴ Favourable outcome = 0
Hence, P (getting a queen) = 04 = 0
