|A|=\binom{10}{4}=\dfrac{10!}{4!6!}=\dfrac{7\cdot8\cdot9\cdot10}{2\cdot3\cdot4}=210\\\\
P(A)=\dfrac{210}{4845}=\dfrac{14}{323}\approx4.3\%$

Paul [167]

Answer:

The total number of cupcakes ordered=216

Step-by-step explanation:

The total number of cupcakes ordered that the baker completed can be expressed as;

C=P×t

where;

C=Total number of completed order of cupcakes

P=percentage of order completed

t=total number of ordered cupcakes

In our case;

C=81

P=37.5%

t=t

replacing in the above expression;

81=37.5%×t

(37.5/100)×t=81

t=81×100/37.5

t=216

The total number of cupcakes ordered=216
