Answer:
Option B is right
Step-by-step explanation:
P(A or B)
In set theory if A and B are two sets we have either A occurs or B occurs or both as
P(A or B) = P(AUB)
This implies that A occurs or B occurs
Probability is calculated as P(A)+P(B)-P(AB)
P(AB) here represents both occurring and this is subtracted as this was added two times
Option A is wrong because this is AB
Option C is wrong because it is not necessary A occurs first
D is wrong because this is A'UB' where A' represents the complement of A
So correct answer out of four options is
B. the probability that in a single trial, event A occurs, event B occurs, or they both occur.
Answer:
1936
Step-by-step explanation:
x² + 87 = (x +1)²
x² + 1)² - x² =87
(x² + 2x +1) = 87
2x + 1 = 87 ⇒ x = 44
44² = 1936
Your answer is false the upper quartile is the median as in middle number not mode.
