Answer:
D) 0.1250
Step-by-step explanation:
Let P(J) = Probability of John to purchase 0 books
Let P(B) = Probability of Beth to purchase 0 books
P(J∩B) = Probability that both john and Beth will purchase 0 books .ie. a total of 0 books is purchased.
Since the decisions to purchase books are two independents events,
P(J∩B) = P(J) * P(B)
P(J) = 0.5
P(B) = 0.25
P(J∩B) = 0.5 * 0.25
P(J∩B) = 0.125
Lets solve your equation step by step:
(4k + 5)(k + 1) = 0
Step 1: Simplify both sides of the equation:
4k^2 + 9k + 5 = 0
Step 2: Factor left side of equation:
(4k + 5)(k + 1) = 0
Step 3: Set factors equal to 0:
4k + 5 = 0 or k + 1 = 0
k = - 5/4 or k = - 1
Answer: k = - 5/4 or k = - 1
Hope that helps!!!! ( Answer: k = -5/4 or k = -1)
