Answer:
B) 1
Step-by-step explanation:
Given:
We need to solve the given expression.
Now We know that when base of the exponents then the law of indices applied for the same.
Now According to Law of Indices.
On Solving the above expression we get;
Hence The Simplified form of given expression is 1.
Answer:
And then replacing in the total probability formula we got:
And rounded we got
That represent the probability that it rains over the weekend (either Saturday or Sunday)
Step-by-step explanation:
We can define the following notaton for the events:
A = It rains over the Saturday
B = It rains over the Sunday
We have the probabilities for these two events given:
And we are interested on the probability that it rains over the weekend (either Saturday or Sunday), so we want to find this probability:
And for this case we can use the total probability rule given by:
And since we are assuming the events independent we can find the probability of intersection like this:
And then replacing in the total probability formula we got:
And rounded we got
That represent the probability that it rains over the weekend (either Saturday or Sunday)
