Answer:
The experimental probability of landing on heads is 0.3
Step-by-step explanation:
We are given the following in the question:
Number of heads = 30
Number of tails = 70
Talia said the probability of getting heads is [tex]\frac{30}{70}[/tex].
She evaluated the wrong probability.
She did not considered total number of trials in the experiment.
Formula for probability:
[tex]\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}[/tex]
Probability of heads =
[tex]P(H) = \dfrac{30}{30+70} = \dfrac{30}{100} =0.3[/tex]
The experimental probability of landing on heads is 0.3
