Answer:
16
Step-by-step explanation:
ratio is 5:4:1
David: Malachy: Paul
David gets 20 (that is 4 times more than the original ration. so need to multiply everything by 4)
4*4=16
1*4=4
new ration- 20:16:4
So David gets 20
Malachy gets 16
Paul gets 4
0.25 cent per ounce because 16 ounce in a pound so 16 x 7 = 112 $28 divided by 112 is 0.25
In probability and statistics, there is an equation used for repeated trials. In this equation, you find the probability of getting 'r' successful events out of 'n' trials. Moreover, you should incorporate the probability of the success per trial. For a 6-sided face, each side has a probability of success of 1/6. On the other hand, the probability of each side not appearing is 5/6, because when you add these two, it would sum up to 1 as always.
Now, the equation for repeated trials is:
Total Probability = n!/r!(n-r)! * p^(n-r) * q^r
where
n = 5 tosses
r = 1 and 2 (since you want to see the probability of a side less than 3)
p = 1/6
q = 5/6
So, you add the individual probability when r=1, and when r=2.
Total Probability = 5!/1!(5-1)! * (1/6)^(5-1) * (5/6)^1 + 5!/2!(5-2)! * (1/6)^(5-2) * (5/6)^2
Total Probability = 50/243 or 20.58%
Yes, the larger one is twice the smaller one.
8*2=16
5*2=10
