Suppose a game uses a spinner with five equal sections numbered 1–5 to determine the value of tokens given to the player spinning it. what is the expected value of the number of tokens?

Answer with explanation:

Number of sections on the spinner=5={Marked as ,1,2,3,4,5}

When the spinner is Spun once

Probability of getting any of 1,2,3,4, and 5

As, it is not given, that if a player spun a Spinner and get, either of,1,2,3,4,or.5, on each section how many token someone is getting.

Suppose player landing on section 1 is getting token=1, Player landing on section 2 is getting token =2,..............

So, Expected value can be Calculated by,the following method

E(x)=x × P(x)

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:
