In the early months of some year one site added 0.4 million new accounts every day, At this rate , how many days would be needed to add 24 million new accounts?
The table have the following results:
Hearts – 7
Diamonds – 4
Clubs – 8
Spades – 5
There is a total of 24
The question is asking for the probability of not
selecting a heart.
So we need to add the probabilities of the diamonds,
clubs, and spades since these suits are different from hearts.
So = 4 + 8 + 5 = 17
And we have a total of 24 cards
<span>Therefore the probability is 17/24. </span>
So remember that (a/b)(c/d)=(ac)/(bd)
convert to imporoper number for easy
4 and 1/4=4+1/4=16/4+1/4=17/4
2 and 2/3=2+2/3=6/3+2/3=8/3
length times base=17/4 times 8/3=
(17 times 8)/(4 times 3)=
136/12=
34/3=
33/3+1/3=
10+1/3=
10 and 1/3 square yards
area is 10 and 1/3 square yards
