Me this is a huge grade for me! which table is a probability distribution table?

Step-by-step explanation:

This problem is solved by applying probabilities definition, which is the positive quotient between possible events and all events.

However, the important thing here is that probabilities never can be negative, they can go from 0 to 1, that's it. So, all tables that have negative numbers, means that they have negative "probabilities", which is impossible, that means that they are no probabilities.

Therefore, the right table is the last one, because it contains positive numbers, indicating possible probabilities.

sorry

step-by-step explanation:

sorry, but im pretty sure its a now that i look at it

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
