Answer:
it should be 1485
Step-by-step explanation:
You have to multiply
15% is roughly once in seven tries. I'd call that unlikely.
Answer:
P = 12·0.5^11·0.5^1 + 0.5^12 = 13/4096 = 0.0032 = 0.32%
The given polynomial is

As this is a fourth degree polynomial, we can not directly use any formula, So here we will use hit and trial method
check whether x=-1 is a zero of the polynomial or not

Hence x=-1 is not a zero.
Now check whether x=-2 is a zero of the polynomial or not

Hence x=-2 is a zero of the polynomial.
Hence we can re-write the polynomial as

Hence the required binomial is (x+2)
