Answer:
Step-by-step explanation:
From the given information,
Considering both cases when p = 0.5 and when p ≠ 0.5
the probability that the gambler will quit an overall winner is:
where ;
N.k = n and k = m
Hence, the probability changes to:
is p ≠ 0.5 and k/N = 
is P = 0.5
Answer:
CD= 15.03
Step-by-step explanation:
x1=7, x2= -8
y1=-4, y2=-5
distance CD= √(x2- x1) 2+ (y2-y1)2
= √( -8-7)2 + [-5-(-4)]2
= √(15)2+ (-5+4)2
= √225+ (1)2
= √225+1
= √226
= 15.03
Answer:
divide 95÷30% then that will be your answer
Step-by-step explanation:
For example:
Ex: 2:3 :: 6:9
In this question, the means are 3 and 6.
The extremes are 2 and 9.
We use this method to find whether the two ratios are equal or not.
We multiply the means and the extremes, and if there products are same, then these two ratios are proportional.
If these two ratios are proportional, their "means" = "extremes"
=> Means = Extremes
=> 3 x 6 = 2 x 9
=> 18 = 18
So, these two ratios are proportional.
Hope this helps you.
You simply put 40 over a hundred and 55 over n (which is the number were trying to find) so you do cross multiplication. 55 times a hundred and after you get the answer. You divide it by 40 and should get 137.5.
