You toss a fair tetrahedral (4-sided, and the sides are marked "1", "2", "3", and "4") die, and you play the following game repeatedly. For each game, you throw the die n > 3 times. Starting from the third throw of the current game, right after each throw, you will get 1 dollar if the total number of points on the last three throws is 8 or higher, and you pay 1 dollar otherwise. It is possible to verify that your probability of winning one dollar on the third throw is 0.5. The random variable Xi represents the outcome of the i th throw. Required:
Find the expected value of your total gains/losses over one game in terms of n.

3/6   and 9/18

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
