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.

If you have two pennies, the probability of both coming up heads when flipped is _____.

Juli2301 [7.4K]

There are four side to 2 pennies
both (2) coming up head out all the side (4)
there is a 2/4 chance then simplify by dividing by 2/2 and get ½
so you have ½ chance of both becoming heads

Hope this helps :D

Please help I don't understand!

Answer:

Step-by-step explanation:

Here, the sides are in proportion.

⇒ $\frac{24}{k} = \frac{32}{64}$

⇒ $\frac{24}{k} = \frac{1}{2}$

⇒ k = 24 × 2

⇒ k = 48
