An experiment consists of first rolling a die and then tossing a coin: a. How many elements are there in the sample space?

b. Let A be the event that either a 3 or 4 is rolled first, followed by landing a head on the coin toss.
P(A) =
Present your answer as a decimal rounded to four decimal places.

c. Let B be the event that a number less than 3 is rolled, followed by landing ahead on the coin toss. Are events A and B mutually exclusive?

_Yes, they are Mutually Exclusive, or
_No, they are not Mutually Exclusive

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

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.

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

answer: x=3 and y=4
