Hi,
The answer will be

.
Now how is that, there is a rule for the right angled triangle which says:
cosθ =

so, if we applied this rule on the lower triangle we can say: cos30°=

and therefore the hypotenuse =

=

.
now in the upper triangle we will apply the same rule so,
cos45°=

and the adjacent side in the upper triangle is

and the hypotenuse is x.
so cos45°=

and then we can say
x=

=

.

Step-by-step explanation:
Given:
Probability of doing yard work is, 
Probability of raining, 
Probability of doing yard work and it raining is, 
Now, two events A and B are independent if,

Conditional probability of event A given that B has occurred is given as:

So, 
Since,
, A and B are not independent events.
