Answer:
The solutions are correct
Step-by-step explanation:
i) In a year there is a total of 12 months, if ten students can have birthdays in 10 different months, the number of ways this can happen is:
Number of ways = 12 × 11 × 10 × . . . × 3 = 
ii) The number of ways 1 student can have birthday months = 12¹, The number of ways 2 students can have birthday months = 12¹ × 12¹ = 12². Hence:
The number of ways 10 students can have birthday months = 12¹⁰
iii) The probability that no two share a birthday month = 
= 0.00387

Answer:
49
Step-by-step explanation:
The ratio of three numbers = 2:5:7
Then the numbers are 2x,5x and 7x
Given that the LCM of these numbers = 490
LCM of 2x,5x,7x is 2×5×7×x = 70x
Then, we have 70x = 490
x = 7
Hence, the numbers are 14, 35 and 49
Largest number = 49
∴The square root of the largest number = 7
