From the Venn diagram, we can deduce the following:

• Number of participants with drowsiness only = 29

,

• Number of participants with anxiety only = 38

,

• Number of participants who had both = 83

,

• Number of participants who had none = 27

Now, let's answer the following questions.

• (a). How many of the participants had anxiety?

Using the diagram given, the number of participants who had anxiety will be:

Number of both + number of anxiety = 83 + 38 = 121

Therefore, 121 participants had anxiety.

• (b). How many participants had drowsiness or anxiety or both?

To find the number of participants who had drowsiness or anxiety or both, we have:

Drowsiness only + anxiety only + both = 29 + 38 + 83 = 150

Therefore, 150 participants had drowsiness or anxiety or both.

• (c). How many did not have both drowsiness and anxiety?

To find this number, subtract the total number from the number of people who had both.

We have:

Total number of people - number of people who had both = 177 - 83 = 94

Therefore, 94 participants did not have both drowsiness and anxiety.

ANSWER:

• (a). 121 participants

,

• (b). 150 participants

,

• (c). 94 participants
