Given that Erica and AAron,are using lottery system to decide who will wash dishes every night.
They put some red and blue power chips and draw each one. If same colour, Aaron will wash and if not same colours Erica will wash
If the game is to be fair, then both should have equal chances of opportunity for washing.
i.e. Probability for Erica washing = Prob of Aaron washing
i.e. P(different chips) = P(same colour chips)
Say there are m red colours and n blue colours.
Both are drawing at the same time.
Hence Prob (getting same colour) = (mC2+nC2)/(m+n)C2
Probfor different colour = mC1+nC1/(m+n)C2
The two would be equal is mC2 +nC2 = m+n
This is possible if mC2 =m and nC2 = n.
Or m = 2+1 =3 and n =3
That for a fair game we must have both colours to be 3.
Answer:
The answer is= 119 Bushels and a half(119.5)
Step-by-step explanation:
Equation related to the problem= 220-(67/4)·T=bushels of Beans left
After 6 days=
220-(67/4·)6=bushels of Beans left
Bushels of beans left=119.5---> You need to change the dot for a fraction
119.5 is 119 bushes and a half so
The answer is= 119 Bushels and a half(119.5)
Answer:
4×(x+8)=25.
use the 4 to multiply the numbers in the bracket.
which is 4x+32=25.
then collect like terms which is...
4x=25-32...
4x=-7.
x=-7/4= -1.75 or -1 whole number 3/4.
