Answer:
The probability that all 15 will get the type of book they want from current stock is 0.4838.
Step-by-step explanation:
Denote the random variable <em>X</em> as the number of students who want to buy new copy.
The probability of a student wanting to buy a new copy is, P (X) = <em>p</em> = 0.30.
A random sample of <em>n</em> = 15 students is selected.
The random variable <em>X</em> follows a Binomial distribution.
The probability function of a Binomial distribution is:
It is provided that the bookstore has 10 new copies and 10 used copies in stock.
All the 15 students get their desired copy, then this can happen if at most 10 want to buy new copy and at least 5 wants to buy used copy.
Compute the probability of (5 ≤ <em>X</em> ≤ 10) as follows:
P (5 ≤ <em>X</em> ≤ 10) = P (X = 5) + P (X = 6) + P (X = 7) + P (X = 8) + P (X = 9) + P (X = 10)
Thus, the probability that all 15 will get the type of book they want from current stock is 0.4838.
Answer:
<h2>2.5*10^0</h2>Step-by-step explanation:
To write a number in scientific notation or standard form we write the number and multiply it by 10 to the power of any number
The proper format for scientific notation is a x 10^b and it is read "a times 10 to the power of b"
Given the diameter of 2.5
in standard form or scientific notation is
