To find the experimental probability of the family having two dogs or two cats, we need to add the frequencies of the outcomes where they have either two dogs or two cats.
From the data given, the outcomes with either two dogs or two cats are:
- Heads, Heads (12)
- Tails, Tails (9)
Adding the frequencies of these outcomes, we get:
12 + 9 = 21
Therefore, the experimental probability that the family has two dogs or two cats is 21/50 or 0.42 or 42%.
Result Frequency
Heads, Heads 12
Heads, Tails 12
Tails, Heads 17
Tails, Tails 9
Total 50
Based on your data, what is the experimental probability that the family has two dogs or two cats?
