Answer:
![P( A \cap B) = P(A) *P(B) = 0.34*0.32 = 0.1088](https://tex.z-dn.net/?f=%20P%28%20A%20%5Ccap%20B%29%20%3D%20P%28A%29%20%2AP%28B%29%20%3D%200.34%2A0.32%20%3D%200.1088)
And then replacing in the total probability formula we got:
![P(A \cup B) = 0.34+0.32 - 0.1088 = 0.5512](https://tex.z-dn.net/?f=%20P%28A%20%5Ccup%20B%29%20%3D%200.34%2B0.32%20-%200.1088%20%3D%200.5512)
And rounded we got ![P(A \cup B ) = 0.551](https://tex.z-dn.net/?f=%20P%28A%20%5Ccup%20B%20%29%20%3D%200.551)
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:
![P(A) = 0.34 , P(B) = 0.32](https://tex.z-dn.net/?f=%20P%28A%29%20%3D%200.34%20%2C%20P%28B%29%20%3D%200.32)
And we are interested on the probability that it rains over the weekend (either Saturday or Sunday), so we want to find this probability:
![P(A \cup B)](https://tex.z-dn.net/?f=%20P%28A%20%5Ccup%20B%29)
And for this case we can use the total probability rule given by:
![P(A \cup B) = P(A) + P(B) - P(A \cap B)](https://tex.z-dn.net/?f=P%28A%20%5Ccup%20B%29%20%3D%20P%28A%29%20%2B%20P%28B%29%20-%20P%28A%20%5Ccap%20B%29)
And since we are assuming the events independent we can find the probability of intersection like this:
![P( A \cap B) = P(A) *P(B) = 0.34*0.32 = 0.1088](https://tex.z-dn.net/?f=%20P%28%20A%20%5Ccap%20B%29%20%3D%20P%28A%29%20%2AP%28B%29%20%3D%200.34%2A0.32%20%3D%200.1088)
And then replacing in the total probability formula we got:
![P(A \cup B) = 0.34+0.32 - 0.1088 = 0.5512](https://tex.z-dn.net/?f=%20P%28A%20%5Ccup%20B%29%20%3D%200.34%2B0.32%20-%200.1088%20%3D%200.5512)
And rounded we got ![P(A \cup B ) = 0.551](https://tex.z-dn.net/?f=%20P%28A%20%5Ccup%20B%20%29%20%3D%200.551)
That represent the probability that it rains over the weekend (either Saturday or Sunday)
10 cents, cause the {ball +$1.00=$1.10} subtract $1 from both sides the ball=$0.10
mere ko question samjh nahi aaya... plz ek baar phir se likho
Answer:
3
Step-by-step explanation:
Break the problem up into two
Ignore the -1 for now
2+2=4 because if you separate 2 and 2, you get four ones, therefore it's four
Now that you have four, subtract 1
And you got 3
Of 5 out of 12 (5/12) are sports games and 3 out of 12 (3/12) are educational, then you would add these together because you need a total for both because it would include one or the other, so both.
5/12 + 3/12= 8/12 or 2/3 are one or the other.
