Talia tossed a penny many times. She got 30 heads and 70 tails. She said the experimental probability of getting heads was 30 70

-BARSIC- [3]

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 $\frac{30}{70}$ .

She evaluated the wrong probability.

She did not considered total number of trials in the experiment.

Formula for probability:

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

Probability of heads =

$P(H) = \dfrac{30}{30+70} = \dfrac{30}{100} =0.3$

The experimental probability of landing on heads is 0.3
