Answer:

It's odd.

Explanation:

A function is odd when <span><span>f<span>(−x)</span></span>=−<span>f<span>(x)</span></span></span>

<span><span>f<span>(−x)</span></span>=6<span><span>(−x)</span>3</span>−2<span>(−x)</span></span>

<span>=−6<span>x3</span>+2x</span>

<span>=−<span>(6<span>x3</span>−2x)</span></span>

<span>=−<span>f<span>(x)</span></span></span>

Thus, the function is odd.

If a function is odd, then it is symmetric over the x-axis.

P( rolling a number greater than 2 and the coin landing on heads or tails)
irina [24]

The value of P(rolling a number greater than 2 and the coin landing on heads or tails) is 4/6

<h3>How to determine the probability?</h3>

The given parameters are:

Objects = Dice and Coin

The sample space of the objects are:

Dice = {1, 2, 3, 4, 5, 6}

Coin = {Head, Tail}

From the above sample spaces, we have:

P(Rolling a number greater than 2) = 4/6

P(Coin landing on heads or tails)  = 1

The required probability is then calculated as:

P(rolling a number greater than 2 and the coin landing on heads or tails) = P(Rolling a number greater than 2) * P(Coin landing on heads or tails)

Substitute the known values in the above equation

P(rolling a number greater than 2 and the coin landing on heads or tails) = 4/6 * 1

Evaluate the product

P(rolling a number greater than 2 and the coin landing on heads or tails) = 4/6

Hence, the value of P(rolling a number greater than 2 and the coin landing on heads or tails) is 4/6
