Question 404888: Assume that there is an equally likely chance of being born on any particular day of the week.
What is the probabilty that a person selected at random was not born on a Tuesday?
What is the probabilty that, of any two people selected at random, exactly one was born on a Tuesday Answer by sudhanshu_kmr(1152) (Show Source):
You can put this solution on YOUR website! 1)
Probability that a person selected was born on Tuesday P(A)= 1/7
probability that not born on Tuesday P'(A) = 1- P(A) = 6/7
2)
Probability that among 2 people,
first born on Tuesday and second on other day = 1/7* 6/7 = 6/49
first born on other day and second on Tuesday = 6/7 * 1/7 = 6/49
probability that exactly one was born on a Tuesday = 6/49 + 6/49 = 12/49
