Respuesta :

three out of ten times

Answer:

3/10

Step-by-step explanation:

If the probability of losing is 7/10, then the probability of winning is 3/10. To find out the probability of winning we just have to subtract the probability of losing from the total which is 10:

10/10 = total probability

7/10 = probability of losing

Probability of winning is 3/10.
