All these cases represent experiments whose outcomes are all equaly likely. What we mean is that the cards have all the same probability of being dealt (1/52), and all the spaces of the spinner have the same probability of being landed into (1/5).
These probabilities are computed as 1 over all the possible outcomes.
(a) If you want a heart card and a five, you want the 5 of hearts. So, only one card would satisfy your request, and thus you have probability 1/52 of dealing the 5 of hearts.

(b) There are four 10s and four Jacks in the deck, so 8 cards satisfy your request. With probability 8/52, you'll be dealt a Jack or a 10.

(c) You have two "good" outcomes out of 5, so your probability is 2/5.

Answer:
the image is upside down
Step-by-step explanation:
Given :-
... ( 2x + 3y - 4z ) - ( x - y - z )
... 2x + 3y - 4z - x + y + z
... x + 4y - 3z is the answer.
Hope it helps!
I’m not 100% sure but isn’t it x2 +xy +y2?
A statistical question is a question that is based off of data. People commonly use numerical data as well. It’s common for a statistical question to have more than one answer. This is because all the data is recorded and used into central tendency data.
