Timings given by

2:31
3:13
3:55
4:37

Find sum

2:31=2+3+1=6
3:13=3+1+3=7
3:55=3+5+5=13
4:37=4+3+7=14

The next watch should show the time whose sum is 14+1=15

Coming to 1st watch

5:19=5+1+9=15

Hence option A is correct

Spare way

Although there is another way .

We can observe that each timings are 42mins ahead from before.

Hence

Last time would be 4:37+0:42=5:19

Answer:

$\frac{(C_{8|2}) (C_{5|2} ) + (C_{8|3} )(C_{5|1} )+ C_{8|4}}{C_{13|4} }$

Step-by-step explanation:

The total amount of students in the pool is 13.

1) Find the probability that at least 2 first year graduate students are among the chosen group.

The total amount of different ways to chose 4 students from a pool of 13 is $C_{13|4}$

The total amount of ways to choose at least 2 first year graduate students would be:

Ways of choose 2 first year students and 2 seniors + ways of choose 3 first year students and 1 senior + ways of choose 4 first year students. <u>(we are adding and not multiplying because it's "choose 2 first year OR 3 OR 4")</u>

Therefore, the probability would be:

$\frac{(C_{8|2}) (C_{5|2} ) + (C_{8|3} )(C_{5|1} )+ C_{8|4}}{C_{13|4} }$
