#### Solution

Total number of cards = 49

Total number of outcomes = 49

The odd numbers form 1 to 49 are 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47 and 49.

Total number of favourable outcomes = 25

∴ Required probability `="Total number of favourable outcomes"/"Total number of outcomes"=25/49`
