zhuklara [117]

Answer:

\frac{1}{8}

Step-by-step explanation:

Alice and Bill  are planning to have three children

We have to find the probability that all three of their children will be girl.

Sample space =S={BBB,BBG,BGB,GBB,GGG,GBG,GGB,BGG}

Total =8

Number of cases in which all three children are girls={GGG}

Probability,P(E)=\frac{number\;of\;favorable\;cases}{Total\;number\;of cases}

Using the formula

Then , the probability that all three of their children will be girls=\frac{1}{8}

Which of the following rotational symmetry is applied to the isosceles triangle​
ioda

Answer:

Rotational symmetry of 180° about the origin: Yes.

Rotational symmetry of 270° about the origin: No.

Explanation:

A figure is a rotationally symmetrical if it look the same after a given turn.

We have to analyze if the parallelogram has rotational symmetry of 180° or 270°. picture the figure rotating a given amount of degrees to see if it looks the same or not.

180 degree rotation:

We can see that the figure looks the same after a 180° rotation.

270 degree rotation:

We can see that the figure does not look the same after a 270° rotation.

So the answer will be:

Rotational symmetry of 180° about the origin: Yes.

Rotational symmetry of 270° about the origin: No.
