Sinx = 4/5, cosx = 3/5 and tanx = 4/3
Answer:
When you have multiple events (here each flip of the coin is a individual event) the probability of all the events (or the joint probability) is equal to the product of the probabilities of each event.
For example, with a fair coin the probability of getting heads is 0.50
If you get heads 3 times, and you add the probabilities you get:
0-50*3 = 1.50
this has no sense, because the probability must be a number between 0 and 1.
The actual probability is:
P = 0.50*050*0.50 = 0.125
I don't have a lot of experience with chance, but there are 2 odd numbers before 4, 1 and 3, so it would be 2 out of 6 or 33.3 continuing percent.
Answer:
D
Step-by-step explanation:
It makes the most sence.
To find a fraction of a fraction, what you have to do is multiply. You're looking for
of
so you're equation is going to be
×
=
To multiply fractions, you multiply straight across (numerator x numerator, denominator x denominator):
×
=
quart or
quart
This makes more sense when you draw a picture. First starting by drawing what you're taking a fraction of, which is
. Then you split the entire whole into fourths to find what
is. See the attached picture. :)
