扇形统计图展示了一群孩子选择的他们最喜欢的颜色。相同的信息也展示在条形统计图中，但条形统计图上没有显示颜色的名称。 有多少个孩子选择黄色和红色作为他们最喜欢的颜色？

1. Read the values from the bar graph

The lengths of the four bars are $8$, $12$, $20$, and $32$.

2. Match the colours to the bar values using the pie chart's relative sizes

From the pie chart, the sectors in increasing order of size are Blue, Red, Green, and Yellow.
Matching these to the bar values in increasing order:

• Blue = $8$
• Red = $12$
• Green = $20$
• Yellow = $32$

3. Calculate the total number of children who chose yellow and red

$\text{Yellow} + \text{Red} = 32 + 12 = 44$
