Since the events are mutually exclusive, then:

So, we have:

Take LCM



Look like both B and D are correct answers. because 23*400=9200 and 26*400=10400
Answer:6√3
Explanation:Before we begin, remember the following:
Now, for the given:75 can be written as 25*3
This means that:

Applying the above concept, we can find that:

Now, we know that:
√25 = 5 (we ignored the negative value)
This means that:
√75 = 5√3
Finally, we can compute the needed sum as follows:
√75 + √3 = 5√3 + √3 = 6√3
Hope this helps :)
the answer is 72
