Answer- 11880
After removing all queens we have 12 types of cards left.
So, total number of unique four card combination will be =
12C1 * 11C1 * 10C1 * 9C1 = 11880, where nCr = n!/ r!* (n-r)!

Answer:
x=8
Step-by-step explanation:
5(x/2+3)=35
x/2+3=35/5
x/2+3=7
x/2=7-3
x/2=4
x=4*2
x=8
Answer:
468
Step-by-step explanation:
Formula for infinite sum of geometric series is;
S_∞ = a1/(1 - r)
Where;
a1 is first term
r is common ratio
We are given;
a1 = 156
r = ⅔
Thus;
S_∞ = 156/(1 - ⅔)
S_∞ = 156/(⅓)
S_∞ = 468
