For Q9, the experimental probability of a mother having 1 child is 4 over 25. In Q10, the experimental probability of landing on 2 is 1 over 5.
Q9: Experimental Probability of a Mother Having 1 Child
To find the experimental probability of a mother having 1 child, we divide the frequency of mothers with 1 child by the total number of mothers surveyed. In this case, the experimental probability is 8 divided by 50, which simplifies to 4 over 25.
Therefore, the experimental probability of a mother having 1 child is 4 over 25.
Q10: Experimental Probability of Landing on 2
For a number cube rolled 25 times with 2 landing five times, the experimental probability of landing on 2 is calculated as 5 divided by 25, which simplifies to 1 over 5.
Hence, the experimental probability of landing on 2 is 1 over 5.
