Respuesta :
Form the given probability distribution, the probability of selling exactly one batch by baker is equal to 0.10.
As given in the question,
Probability distribution established by baker :
x : 1 2 3 4
P(x) : 0.10 0.30 0.40 0.20
As it is give that number of batches made by baker to sell muffins .
For selling 1 batch x = 1.
For selling 2 batch x = 2.
For selling 3batch x = 3.
For selling 4 batch x = 4
Probability of selling exactly one batch by baker is given by when x =1
Probability of x = 1 is given by :
P( x = 1 ) = 0.10
Therefore, form the given probability distribution, the probability of selling exactly one batch by baker is equal to 0.10.
The complete question is :
A baker is deciding how many batches of muffins to make to sell in his bakery. He wants to make enough to sell every one and no fewer. Through observation, the baker has established a probability distribution. x P(x) 1 0.10 2 0.30 3 0.40 4 0.20 What is the probability the baker will sell exactly one batch.
