Question

Let X represent the number of tires with low air pressure on a randomly chosen car.

Answer 1

`\text{ P\lparen Greater than or equal to zero\rparen = 1}`

Step-by-step explanation:

Here, we want to get the probability of X greater than or equal to zero

Mathematically, what we have to do here is to add the probabilities of values for which we have X equals zero or greater

We have this as:

`\begin{gathered} \text{ P\lparen Greater than or equal to zero\rparen = P\lparen0\rparen + P\lparen1\rparen + P\lparen2\rparen + P\lparen3\rparen + P\lparen4\rparen} \\ =\text{ 0.1 + 0.3 + 0.2 + 0.1 + 0.3 = 1.0} \end{gathered}`
