Required probability:

• P = 5/10 = 1/2 or 50%

Answer 2

Answer:

Probability of students will prefer ice-skating over roller - skating = 50 % or 1/2 %

Step-by-step explanation:

No. of 13 yrs old students = 10

No. of those students prefer ice - skating = 5

Probability of students will prefer ice-skating over roller - skating = No. of 13 yrs old students/ No. of those students prefer ice - skating

P = 5 / 10 = 1/2 % = 50 %
