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
Answer:i think d.please dont blame me im not sure.sorry
Step-by-step explanation:
By taking the height of the dad and mom 6²3/8 minus 5²5/8
We can separate the 6² and 5², which will give us 1² then look at the 3/8 minus the 5/8, this equals 2/8, which is 1/4. So the difference is 1²1/4
