Answer:
a) 4/27
b) 1/3
c) 6/27
Step-by-step explanation:
HI!
a)
The event A has only one member:
T T H
Therefore:
P(A) = P(T)P(T)P(H) = (2/3)(2/3)(1/3) = 4/27
b)
For event B, we are only interested in the last toss
x x H
Since the first two tosses are not important for event B they do not contribute to P(B)
P(B) = 1 * 1* P(H) = 1/3
c)
The following are elements of C:
H H T
H T H
T H H
Therefore:
P(C) = P(HHT) + P(HTH) + P(THH)
We can easily see that the probability of the three members is the sam:
P(HHT) = (1/3) (1/3) (2/3) = 2/27
P(HTH) = (1/3) (2/3) (1/3) = 2/27
P(THH) = (2/3) (1/3) (2/3) = 2/27
Therefore:
P(C) = 3 P(HHT) = 6/27
Answer:
Step-by-step explanation:
Let the hypotenuse of the smaller triangle be h units.
Then; from the Pythagoras Theorem.
From the smaller triangle;
and
From the second triangle, let the other other shorter leg of the second triangle be s units.
Then;
and
We now use the double angle property;
we plug in the values to obtain;
Answer: y/2
Step-by-step explanation:
Since the x would equal to 3’s and the y equals to 2’s then it would basically be simplified to y/2

Answer:
5530.50 pesos
Step-by-step explanation:
What you need to do is multiply 450 by 12.29 because each dollar is worth 12.29 and so you need to do this 450<em> </em><u>times</u>.
