You play a game where you are to guess under which of 4 cups a coin has been placed. how many times would you expect to guess correctly in 20 plays of the game? note that the coin is moved after each play.

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.
