Answer:

133/152

Step-by-step explanation:

The probability of 2 independent events is the product of the individual events.  Independent means the first event has no effect on the probability of the second event.  Since we are replacing the first marble, the first even has no effect on the probability of the second event.  

There are 48 total marbles

Let A = pulling a blue marble

Let B = pulling a red marble

So

P(A) = 14/48

P(B) = 19/48

and

P(A then B) = (14/48)(19/48) = 266/2,304 = 133/1,152

A discrete random variable involves two key factors ; discrete and randomness ; Hence, a discrete random variable should have a finite or countable Number of outputs or values. It should also stem from a random procedure. Here, the height of the next hundred babies is a random procedure as the next 100 babies in the region are unknown until Given birth too and as such all pregnant women have the chance of having their babies among. Since, we are dealing with exact height values which are countable (100), then we this is a discrete random variable.
