Probability =
(number of ways to succeed) / (total possible outcomes) .
There are 6 total possible outcomes of rolling one honest die.
Only one of them is a ' 4 '.
-- So the probability of rolling a '4' on the first roll is 1/6 .
-- The probability of rolling a '4' on the second roll is 1/6 .
-- The probability of BOTH events is
(1/6) x (1/6) = 1/36 = (2 and 7/9) percent .
Assuming There is ONLY ONE CORRECT ANSWER,
The probability of her guessing the answer without ruling out the choices is 1/5.
if 3 choices are ruled out, then 1 out of the remaining two is right, which gives the probability 1/2
now, 1/5 = 20% , while 1/2 = 50%.
Therefore her probability of getting the correct answer improves by 30% [ not much in a REAL test though :P ]
Because to find the perimeter of a shape you have to add all the sides together so you would take 26.46 and divide it by 4 (since squares have 4 sides) to get 6.165
Answer:
B and D
Step-by-step explanation:
Geometric sequences and series. A geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio, r.
an = ar^(n-1)
d) 1/3, 2/3, 4/3, 8/3, 16/3, . . . .
1/3 * 2 = 2/3
2/3 * 2 = 4/3
4/3 * 2 = 8/3
where r = 2, constant multiplier is 2. //Answer
b) 320, 80, 20, 5, 1.25, . . . . .
320 * 1/4 = 80
80 * 1/4 = 20
20 * 1/4 = 5
r = 1/4 //Answer
Answer: B and D
//Hope this helps.
