Question

Rita rolled a die 25 times. Her results are shown in the table attached:

1. What is the experimental probability P(2)?


2. What is the experimental probability P(4)?


3. What is the experimental probability of rolling a 2 or a 3?


4. What is the experimental probability of rolling an even number?


5. What is the theoretical probability of rolling an even number?


6. Find the experimental probability P(1, 2, 3, 4, 5, 6).


7. Find the theoretical probability P(1, 2, 3, 4, 5, 6).

Answer 1

I have the same questions and I got them right

Explanation:

1.) P(2)=4/25

2.) P(4)= 5/25= 1/5

3.) P(2,3)=5/25= 1/5

4/25+1/25= 5/25= 1/5

4.) P(2,4,6)=16/25

4/25+ 5/25+ 7/25= 16/25

5.)There are three even numbers so, 3/6= 1/2. So, 1/2.

6.) P(1, 2, 3, 4, 5, 6)= 25/25 = 1

6/25+ 4/25+ 1/25+ 5/25+ 2/25+ 7/25= 25/25 = 1

P(1)= 6/25 P(2)= 4/25 P(3)= 1/25 P(4)= 5/25 P(5)= 2/25 P(6)= 7/25
