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:
<u>Yes</u>
Step-by-step explanation:
<u>When there are 2 rows</u>
- Number of erasers per row = No. of erasers / No. of rows
- Number of erasers per row = 18/2
- Number of erasers per row = 9
<u>When there are 3 rows</u>
- Number of erasers per row = No. of erasers / No. of rows
- Number of erasers per row = 18/3
- Number of erasers per row = 6
<u>Therefore, there will be more erasers per row in 2 equal rows than in 3 equal rows.</u>
Answer:
a = 16
Step-by-step explanation:
6 = a/4 + 2
Switch sides.
a/4 + 2 = 6
Subtract 2 from both sides.
a/4 = 4
Multiply both sides by 4.
a = 16
