Answer:
0.25 = 25% probability that it will rain today and ruin your picnic
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Cloudy skies
Event B: Rain
20% of all days start with clouds in the air
This means that 
50% of rainy days start with rain clouds in the air
50% of 10%. So

What is the probability that it will rain today and ruin your picnic

0.25 = 25% probability that it will rain today and ruin your picnic
You would have to add x1 + x2 and divide by 2. do the same with y1 and y2.
(1/2,-1/2)
