Respuesta :

The odd against winning a prize in the raffle are 9:1. So, the number of unfavourable outcomes are 9 and the number of favourable outcomes are 1. The number of total outcomes are 10. Therefore, the probability of winning a prize is 1/10 that is equivalent to 0.1.

Thus, option B is correct.
