Answer: 4, 800
Step-by-step explanation:
Answer: 81 people attended
Explanation:
Number of adults = 988 / 26 = 38
Number of students = 731 / 17 = 43
Total attendees: 38 + 43 = 81
The sum of 14 and 16 is 30.30 times 4 is 120.
<span>(<span>14+16</span>)</span><span>(4)
</span><span>=<span><span>(30)</span><span>(4)</span></span></span><span>=
<span>120</span></span>
This is a combination problem.
The formula is n! / (r!(n-r)!
where n is the total number of people and r is the number of people to be picked.
n = 15, r = 4
15! / (4!(15-4)!)
15! / (4!*11!)
Total combinations = 1,365
