Removing the time spent on riding the trolley:
90-36=54
And the rest of the time on the sights
Then 54/9= 6
They stopped at 6 sights
This can be solve
using systems of linear equation
Let x be the number
of milk chocolate candy bar sold
Y be the number of
white chocolate sold
X + y = 330
2x + 3y = 900
X = 90
Y =240 white

Answer:
See below in bold.
Step-by-step explanation:
For the fair coin Prob(head) = 1/2 and Prob(Tail) = 1/2.
For the biased coin it is Prob(head) = 2/3 and Prob(Tail) = 1/3.
a) Prob(2 heads) = 1/2 * 2/3 = 1/3.
b) Prob(2 tails) = 1/2 * 1/3 = 1/6.
c) Prob(1 head ) = Prob(H T or T H) = 1/2 * 1/3 + 1/2 * 2/3) = 1/6+1/3 = 1/2.
d) Prob (at least one head) = prob (HH or TH or HT) = 1/3 + 1/2 =<em> </em>5/6.
Answer:
c x ≤ 6
Step-by-step explanation:
2x ≤ 12
Divide each side by 2
2x/2 ≤ 12/2
x ≤ 6
