Answer:
$540
Step-by-step explanation:
1 member 1 day :$480/80/20 = $3
12 members 15 day = $3 * 12 * 15 = $540
Hope this helps!!!
Answer:
10%
Step-by-step explanation:
Since the question is not complete, I will be solving for probability of 3 9s
To solve this, we would be using the principle of combination, and thus
A deck of 52 hours has 4 nines, the probability that it contains at least 3 9s is mathematically represented by the equation.
P ( x ≥ 3 ) = ( 48 C 10 · 4 C 3 ) / ( 52 C 13 ) + ( 48 C 9 · 4 C 4 ) / ( 52 C 13 )
Remember I told us were going to be using the principle of combination. Well then
nCr = n!/r!(n - r)!
Now, applying the above stated formula to the equation, we have
48C10 = 48!/10!(38!)
4C3 = 4!/3!(1!)
52C13 = 52!/13!(39!)
48C9 = 48!/9!(39!)
4C4 = 4!/4!(0!)
Solving for each independently, we find that
= 0.0412 + 0.588 = 0.1
