Answer: The required value is P(A ∪ B) = 0.73.
Step-by-step explanation: Given that A and B are two mutually exclusive events where
We are to find the following probability :
P(A ∪ B).
We know that
the intersection of two mutually exclusive events is null event. That is,
A ∩ B = ∅ ⇒ P(A ∩ B) = 0.
From the laws of probability, we have
Thus, the required value is P(A ∪ B) = 0.73.
Answer:
63.2
Step-by-step explanation:
The triangles are similar so corresponding angles are congruent. Angle K corresponds to angle P so the answer is 63.2 degrees.
≈9.38
13² - 9² = x²
189 - 81 = 88
√88 = x
Answer:
x = 56
Step-by-step explanation:
cross multiply. 28 times 2 and 1 times x. set them equal to each other and solve for x to get 56.
