horrorfan [7]

Answer:

(a)  99%

(b)  50%

Step-by-step explanation:

(a) All factorials after 1! have 2 as a factor, so are even. Thus 99 of the 100 factorials are even, for a probability of 99%.

Vlada [557]

The capacity of each bottle is \boxed{\bf6.32{\text{ liters}}}.

Further explanation:

Given:

Julianbought 3.9liters of cranberry juice.

Jay bought 8.74 liters of Apple juice.

They mixed both the juice equally.

Procedure:

1. First find total capacity of both the juice.

2. Now, divide by 2 to find weight of juice in each bottle.

Calculation:

The total juice (in liters) can be obtained by adding both the juice brought by the Julian and Jay.

\boxed{8.74+3.9=12.64}

Therefore, the total juice (in liters) is 12.64 liters.

To obtain the number of liters in each bottle can be obtain by divide the total juice in liter by 2.

\dfrac{{12.64}}{2}=6.32

Therefore the capacity of each bottle of juice is 6.32 liters.

Thus, the capacity of each bottle is \boxed{\bf6.32{\text{ liters}}}.

Method 2:

Simple Method:

The Average of two juices gives the value of number of liters in each bottle.

The average is defined as the sum of the items divide by the number of items.

\begin{aligned}\frac{{8.74+3.9}}{2}&=\frac{{12.64}}{2}\\&=6.32\\\end{aligned}

Thus, the capacity of each bottle is \boxed{\bf6.32{\text{ liters}}}.
