Answer:
a) 2048
b)164
c)54
d) 11
Step-by-step explanation:
a) A coin has two faces.
Outcome possible =2^11= 2048
b) 8 heads possible outcome = 11!/8!3! = 3971688/241/920= 164 ways
c)2 heads outcome= 11!/2!8!= 39716800/725760=54
d) 7 heads= 11!/7!6! =39716800/3628800 = 11
D) you just multiply the numerator and denominator by 6 to get an equivalent fraction
5 * 2 = 10
3^10/3^-2, same base, add
10 - 2 = 8
Solution: 10^8
