Question

A triangle is selected at random getting two right angles in the triangle is an example of an impossible event explain. plss and me fast​

Answer 1

Answer:

Suppose an event E can happen in r ways out of a total of n possible equally likely ways.

Then the probability of occurrence of the event (called its success) is denoted by

\displaystyle{P}{\left({E}\right)}=\frac{r}{{n}}P(E)=nr

The probability of non-occurrence of the event (called its failure) is denoted by

\displaystyle{P}{\left(\overline{{E}}\right)}=\frac{{{n}-{r}}}{{n}}={1}-\frac{r}{{n}}P(E)=nn−r=1−nr

Notice the bar above the E, indicating the event does not occur.

Thus,

\displaystyle{P}{\left(\overline{{E}}\right)}+{P}{\left({E}\right)}={1}P(E)+P(E)=1

In words, this means that the sum of the probabilities in any experiment is \displaystyle{1}1.

hope u have satisfied with this above

Answer 2

Answer:

In a traingle the s of all the angles is always 180°. Now if two sides are right angles i. e. =90° then there will be no third angle which is not possible in a triangle. So probability = No. of possible outcomes/total outcomes

=0
