notice, all you do is, move the factor from the bottom to the top, or from the top to the bottom, and the sign changes, from negative to positive or the other way around, is all there's on that

VARVARA [1.3K]

The plot of the PDF shows the distribution is symmetric. This means that the mean is the same as the median, and that the 50% of the distribution lies to other side of this mean, i.e.

P(X\ge a)=P(X\le a)=0.50

For this distribution, a=3.

Kipish [7]

Answer:

<em>The probability of scoring two goals in both times is</em><em> 0.137 or 13.7%</em>

Step-by-step explanation:

Statistics show that a certain soccer player has a 63% chance of missing the goal each time he shoots.

So P(A)=0.63

Hence, the probability of getting success in his shoots will be,

P(A^c)=1-P(A)=1-0.63=0.37

The probability of scoring two goals in both times is,

=P(A^c)\cdot P(A^c)

=0.37\times 0.37

=0.137

=13.7\%
