Answer 1

Answer:

3/10

Step-by-step explanation:

n(s)=10

n(A)=3

P(A)=N(A)/N(S)

= 3/10

Answer 2

The total number of ways are 120.

Step-by-step explanation:

Consider the provided information.

Since they receive the same award that means we don't care about the order.

So we need to find the number of ways of selecting 3 students out of top 10.

The number of ways are: $^nC_r=^{10}C_3$

$^{10}C_3=\frac{10!}{7!3!}=120$

Hence, the total number of ways are 120.
