Respuesta :
add the total of tosses: (18 + 12 = 30)
divide experimental heads by total tosses
12/30 = 2/5
as a decimal is 0.4

The experimental probability of getting heads is given by: Option B: 0.7
What is experimental probability?
Experimental probability calculates the probability of some event from the results of experiments.
For an event E, we get the experimental probability of that event
[tex]P(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}}[/tex]
For the given case, it is given that:
- Heads: 12
- Tails: 18
The experimental probability for getting heads is ratio of number of times head was obtained to the total number of times tossing occurred.
The coin was tossed 30 times (18 + 12 = 30, assuming no other outcome was there).
Thus, the experimental probability of getting heads is given by
[tex]P(\text{getting heads}) = \dfrac{12}{18} = \dfrac{2}{3} \approx 0.7[/tex]
Thus, the experimental probability of getting heads is given by: Option B: 0.7
