N^2 should be the correct answer. Based on those numbers, it appears that the sum can be found by squaring the term n
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:
61% is a reasonable choice
Step-by-step explanation:
The probability of a strike is 79% or 0.79
=> Independently, the probability of 2 consecutive strikes:
P = 0.79 x 0.79 = 0.6241 ~ 61%
Answer:
The greatest number of people that can attend the meeting on that budget is 116
Step-by-step explanation:
The cost for the meeting is given by the following expression:
cost = 500 + 6*person
Since the budget is $1200 the cost must be at most equal to that, therefore:
1200 = 500 + 6*person
500 + 6*person = 1200
6*person = 1200 - 500
6*person = 700
person = 700/6 = 116.667
Since there can't be a 0.667 person, the greatest number of people that can attend the meeting on that budget is 116
Answer:
Can I get the full question please
Step-by-step explanation:
x + y = 10 - - - 1
x=2y - - - - - 2
Putting the value of x in eqn 1,
2y+y=10
y=10/3
=3.33 yrs
