Answer:
So then the best option would be:
a. 1/25
Step-by-step explanation:
For this case we assume that the sample space for the numbers is :
And the sample space for the numbers is:
Both sampling spaces with a size of 5.
We define the following events:
A="We select a 2 from the numbers"
B= "We select a E from the letters"
We can find the individual probabilities for each event like this:
And assuming independence we can find the probability required like this:
The last probability is the probability of obtain obtain a 2 AND an E
So then the best option would be:
a. 1/25
