Answer:
28
Step-by-step explanation:
probability of getting blue ball is 4/9
total cases = 72
i.e number of blue ball 32
number of red vall is 40
so extra 28 is added
Commutaive property says
ab=ba or expanded to say
abc=cba
associative peropty =
a(bc)=(ab)c
so using that
first mix them up knowing that we can move the parenthaseese
all possible equivelnt ones are
4*(5*3)
(3*5)*4
3*(5*4)
(3*4)*5
3*(4*5)
2.5 b = 27.5
b = 27.5 / 2.5
b = 11
