The card has 4 odd numbers out of a total of 6.
So, the ratio is:
Divide by 2
<em>Hence, the ratio of odd to total is 2 to 3</em>
Answer:
0.497
Step-by-step explanation:
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
From the question :
n = 6 ; x = 3 ; p = 0.42
P(x = 3) +... P(x = 6)
P(x = 3) = 6C3 * 0.42^3 * (1 - 0.42)^(6-3)
P(x = 3) = 20 * 0.074088 * 0.195112
P(x = 3) = 0.28910915712
Then find p(x = 4).. + p(x = 6)
Using a calculator :
P(X >= x) = 0.497
Answer:
332.
Step-by-step explanation:
Let the number of decisions made in 1982-1983 be x.
44.6% = 0.446.
This is a decrease, so the number of decisions announced in 2005-2006 is
(1 - 0.446) * x and this = 184.
0.554x = 184
x = 184/0.554
x = 332.
B because you have to add 30 to 60
