Answer: The required probability of event B is P(B) = 0.37.
Step-by-step explanation: For two events A and B, we are given the following probabilities :
P(A) = 0.34, P(A ∩ B) = 0.27 and P(A ∪ B) = 0.44.
We are to find the probability of event B, P(B) = ?
From the laws of probability, we have
Thus, the required probability of event B is P(B) = 0.37.
Answer:
The solutions are 3 and -5
Step-by-step explanation:
x+3=x^2+3x-12
x^2+2x-15
=(x-3)(x+5)
The probability that a girl will be selected from the class is 0.7
Answer:
f(-2) = -5
f(0) = 5
f(1) = 10
Step-by-step explanation:
f(-2) = 5(-2) + 5 → -10 + 5 = -5
f(0) = 5(0) + 5 → 0 + 5 = 5
f(1) = 5(1) + 5 → 5 + 5 = 10
Answer:
The first graph
Step-by-step explanation:
If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.
