To solve ( 10C3 ), which represents the number of combinations of 10 items taken 3 at a time, you use the formula:
[ nCr = \frac{n!}{r!(n-r)!} ]
For ( 10C3 ), this becomes:
[ 10C3 = \frac{10!}{3!(10-3)!} = \frac{10!}{3! \cdot 7!} ]
Calculating this gives:
[ = \frac{10 \times 9 \times 8}{3 \times 2 \times 1} = \frac{720}{6} = 120 ]
Thus, ( 10C3 = 120 ).
To find (10C3) using Pascal's Triangle, locate the row corresponding to (n=10). The entries in this row represent the binomial coefficients for (n=10). The third entry (starting from (0)) in this row corresponds to (10C3), which is (120). Thus, (10C3 = 120).
There are 10C3 = 10*9*8/(3*2*1) = 120 combinations.
It is 10C3*(1/2)10 = 10*9*8/(3*2*1)*(1/1024) = 0.1172, approx.

The answer depends on the value of c!
There are: 10C3 = 120
There are 10C3 = 10*9*8/(3*2*1) = 120 combinations.
10C3(0.5)^10
It is 10C3*(1/2)10 = 10*9*8/(3*2*1)*(1/1024) = 0.1172, approx.

Rules for exponents. a^(n) X a^(m) = a^(n+m) a^(n) / a^(m) = a^(n-m) (a^(n))^(m) = a^(nm) In all cases the coefficient 'a' MUST be the same value in all cases. Also square root(a) = a^(1/2) cube root (a) = a^(1/3) nth root (a) = a^(1/n) Finally a^(-1/n) = 1/a(n)
