3x(9x² + 11x - 5) + 2(2x³ + 11x - 5x²) - 5x² + 8

Simplify.

27x³ + 33x² - 15x + 4x³ + 22x - 10x² - 5x² + 8

Add like terms.

(27x³ + 4x³) + (33x² - 10x²) + (-15x + 22x) + 8

Simplify.

31x³ + 23x² - 7x + 8

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
