Answer:
0.50
Step-by-step explanation:
Given that a package of self-sticking notepads contains 6 yellow, 6 blue, 6 green, and 6 pink notepads. An experiment consists of randomly selecting one of the notepads and recording its color
The probability that a green notepad is selected given that it is either blue or green is to be found out
Let A = event that selected notepad is green or blue
B = selected notepad is green
The probability that a green notepad is selected given that it is either blue or green is to be found out
= P(B/A)
=P(AB)/P(A)
=Prob (green)/P(green or blue)
=

Answer:
The probability that it will take more than 10 minutes for the next student to arrive at the library parking lot is 0.0821.
Step-by-step explanation:
The random variable <em>X</em> is defined as the amount of time until the next student will arrive in the library parking lot at the university.
The random variable <em>X</em> follows an Exponential distribution with mean, <em>μ</em> = 4 minutes.
The probability density function of <em>X</em> is:
The parameter of the exponential distribution is:
Compute the value of P (X > 10) as follows:
Thus, the probability that it will take more than 10 minutes for the next student to arrive at the library parking lot is 0.0821.
