Answer:
210
Step-by-step explanation:
Here comes the problem from Combination.
We are being asked to find the number of ways out in which 3 students may sit on 7 seats in a row. Please see that in this case the even can not be repeated.
Let us start with the student one. For him all the 7 seats are available to sit. Hence number of ways for him to sit = 7
Let us see the student second. For him there are only 6 seats available to sit as one seat has already been occupied. Hence number of ways for him to sit = 6
Let us see the student third. For him there are only 5 seats available to sit as two seat has already been occupied. Hence number of ways for him to sit = 5
Hence the total number of ways for three students to be seated will be
7 x 6 x 5
=210
3000 is the freaking right answer

Answer:
8 capsules
Step-by-step explanation:
The 100 mL of solution requires 4 capsules for its preparation. (4 × 150 mg = 600 mg). So, twice as much solution (200 mL) will require twice as many capsules. It will take 8 capsules to make 200 mL of solution.
