Suppose that events a and b are mutually exclusive with p(a) = ½ and p(b) = ⅓.

irina1246 [14]

No, a & b are not independent if they're mutually exclusive.

Mutually exclusive means the two events cannot occur simultaneously. So if "a" happens "b" cannot. In contrast, two events are independent if the occurrence of one has no effect on the occurrence of the other.

The other leg is 12cm long.

Step-by-step explanation:

Given,

Hypotenuse = c = 15cm

One leg = a = 9cm

Other leg = b

As the triangle is right angled, therefore, using Pythagoras theorem;

$a^2+b^2=c^2\\(9)^2+b^2=(15)^2\\81+b^2=225\\b^2=225-81\\b^2=144\\$

Taking square root on both sides;

$\sqrt{b^2} =\sqrt{144} \\b=12\ cm$

The other leg is 12cm long.
