Answer 1

Answer:

The probability that a randomly selected person neither like to watch the news from online platforms nor watch news in the morning is 0.6700

Expanation:

Parameters:

54% like to watch online platform

`p\mleft(o\mright)=0.54`

45% like to watch news in the morning

`p\mleft(n\mright)=0.45`

32% like to watch both

`p\mleft(o\cup b\mright)=0.32`

The probability that a randomly selected person neither like to watch the news from online platforms nor watch news in the morning is:

`\begin{gathered} p(o\cap n)=p\mleft(o\mright)+p\mleft(n\mright)-p\mleft(o\cup n\mright) \\ =0.54+0.45-0.32 \\ =0.6700 \end{gathered}`
