The probability is a ratio of the possible events to the total events. The total is 52 cards, so the denominator is 52. The individual properties of the specific cards are the following:
Any face or number cards is 4/52, because there are 4 cards for each symbol. On the other hand, each symbol like heart, diamond, club or spade would each have a probability of 13/52 (counting numbers 2 to 10, Ace card, and the 3 face cards). Also, there are 26 each of red and black cards. Furthermore, the words 'or' and 'and' are hint words. When you see 'or', you have to add their individual probabilities. If you see the word 'and', you'll have to multiply them. With that said, the solution is as follows:
a.) P = 4/52 + 4/52 + 4/52 = 3/13
b.) P = (13/52 + 13/52 + 4/52)(26/52) = 15/52
c.) P = 13/52
d.) P = 13/52 + 13/52 + 13/52 = 3/4
Answer:
1
Step-by-step explanation:
AC = 5, ao AB = 2.
This means B = -1+2 = 1.
Ya that's correct u got the right answer
It is only 1 proportion, and it is 1 problem.
10 8
---- = ---
X 4
1). It is 8x=40
2). Divide both sides
by 8
3). X=5
Answer:
56 bags of a chocolate and a popsicle
Step-by-step explanation:
The first thing is to find the relationship between the number of popsicles and the number of chocolates, which would be the quotient of these:
100/56 = 1.78
Since it does not reach number two, you cannot add 2 popsicles and 2 chocolates, therefore the only way that they contain the same amount is that there is a chocolate and a popsicle, that is to say that a total of 56 bags would come out.
