The probability distribution function for the discrete random variable where x is equal to the number of red lights drivers typi

Ivahew [28]

Using probability concepts, it is found that:

a) The missing value is 0.04.

b) The mean is of 0.37.

The distribution is given by:

$P(X = 0) = 0.76$

$P(X = 1) = 0.15$

$P(X = 2) = 0.05$

$P(X = 3) = x$

Item a:

The sum of all the probabilities has to be 1, that is:

$\sum_{i = 0}^{3} P(X = i) = 1$

Thus:

$0.76 + 0.15 + 0.05 + x = 1$

$0.96 + x = 1$

$x = 0.04$

The missing value is 0.04.

Item b:

The mean is given by the sum of each outcome multiplied by it's probability, thus:

$E(X) = 0(0.76) + 1(0.15) + 2(0.05) + 3(0.04) = 0.37$

The mean is of 0.37.

20 Fuji apples cost $12. How many Fuji apples can you buy for $3?

ryzh [129]

Answer:

5 apples

Step-by-step explanation:

First, we must find the cost of one apple

12/20 = the cost of one apple

= $0.60

Then, we divide 3 by the price of one apple

3/0.6 = amount of apple we can buy

= 5
