Answer:
the probability is 0.311 (31.1%)
Step-by-step explanation:
defining the event L= being late to work :Then knowing that each mode of transportation is equally likely (since we do not know its travel habits) :
P(L)= probability of taking the bicycle * probability of being late if he takes the bicycle + probability of taking the car* probability of being late if he takes the car + probability of taking the bus* probability of being late if he takes the bus +probability of taking the train* probability of being late if he takes the train = 1/4 * 0.75 + 1/4 * 0.43 + 1/4 * 0.15 + 1/4 * 0.05 = 0.345
then we can use the theorem of Bayes for conditional probability. Thus defining the event C= Bob takes the car , we have
P(C/L)= P(C∩L)/P(L) = 1/4 * 0.43 /0.345 = 0.311 (31.1%)
where
P(C∩L)= probability of taking the car and being late
P(C/L)= probability that Bob had taken the car given that he is late
Answer:
option B)
x = 2
Step-by-step explanation:
Given in the question the equation:
10x - 3(x- 6) = x + 30
Simplify the left side
10x - 3(x - 6) = x + 30
10x - 3x + 18 = x + 30
rearrange the terms and containing x to the left side of the equation and add accordingly
x(10 - 3 - 1) = (30 - 18)
x(10 - 4) = (12)
x(6) = 12
6x = 12
Divide each term by 6 and simplify
x = 12/6
x = 2
