The formula
for probability is:
Probability
= number of successful events / number of total events
In this
case, the number of total events is equivalent to the total number of peas.
number of
total events = 402 + 38
number of
total events = 440 peas
Since we
want to estimate the probability of getting a green pea, therefore
number of
successful events = 402 green peas
Using the
formula, the probability for getting a green pea is:
Probability
= 402 / 440
<span>Probability
= 0.91 (ANSWER)</span>
<span>The result
is not reasonably close to the value of ¾ or 0.75.</span>
<span> A negative power means the quantity is
in the denominator of a fraction.
(2) to the -1 power means 1/2
6 to the -3 power means 1/(6 to the 3 power).
13xy to the -8 power
means 1 / (13xy to the 8 power)</span>
That's something like 1 / [ (13 to the 8 power) (x to the 8 power) (y to the 8 power) ]
Let us make the denominators all the same so we can compare the fractions easily. We have 1/8, 1/4, 1/2, 5/8, and 7/8. It will be easiest if we change the denominators to 8. Three of the fractions already have a denominator of 8, so we only have to change two. 1/2 equals 2/4 equals 4/8. 1/4 equals 2/8.
Now we can compare the fractions easily. We have 1/8, 2/8, 4/8, 5/8, and 7/8. We see that 7/8 is the greatest fraction.
I hope that this helped you!
