Answer:
True
Step-by-step explanation:
If two events X and Y are mutually exclusive,
Then,
P(X∪Y) = P(X) + P(Y)
Let A represents the event of a diamond card and B represent the event of a heart card,
We know that,
In a deck of 52 cards there are 4 suit ( 13 Club cards, 13 heart cards, 13 diamond cards and 13 Spade cards )
That is, those cards which are heart can not be diamond card,
⇒ A ∩ B = ∅
⇒ P(A∩B) = 0
Since, P(A∪B) = P(A) + P(B) - P(A∩B)
⇒ P(A∪B) = P(A) + P(B)
By the above statement,
Events A and B are mutually exclusive,
Hence, the probability of selecting a 4 of diamonds or a 4 of hearts is an example of a mutually exclusive event is a true statement.

Answer:
1) 80
2) 44
3) 93
4) 47
5) 29
6) 74
7) 60
8) 110
9) 50
Step-by-step explanation:
Each triangle MUST add up to 180, meaning you add the two values given and then subtract that answer from 180 to get the unknown value.
A counterexample would be 4.
4 is divisible by 4 but 4 is not divisible by 8.
12 is divisible by 4 but 12 is not divisible by 8.
20 is divisible by 4 but 20 is not divisible by 8.
