Question 1161573
<br>
It appears you are misunderstanding the given data....<br>
A regular die was rolled multiple times. It came up 1 6 times, 2 4 times, 3 1 time, 4 5 times, 5 2 times, and 6 an unknown number of times.<br>
None of the three questions can be answered with the given information.  We either need to know the number of times a 6 came up, or we need to know the total number of times the die was rolled, so that we can determine the number of times a 6 came up.<br>
1. If your answer of 3 is correct, then the total number of rolls was 6+4+1+5+2+3 = 21.  Was that total number of rolls given, and you forgot to include that information in your post?<br>
For 2 and 3, the experimental probability is the number of times a certain number came up, divided by the total number of rolls.<br>
Assuming the total number of rolls was in fact 21...<br>
2. P(2) = 4/21
3. P(4) = 5/21<br>
----------------------------------------------------<br>
The reader responded saying that the die was rolled 25 times.<br>
So, since the number of rolls other than 6 is 18, the answer to question 1 is that a 6 was rolled 7 times.<br>
And then the answers to questions 2 and 3 are 4/25 and 5/25 = 1/5.<br>
