This is a problem of Standard Normal distribution.
We have mean= 12 grams
Standard Deviation = 2.5 grams
First we convert 8.5 to z score. 8.5 converted to z score for given mean and standard deviation will be:
So, from standard normal table we need to find the probability of z score to be less than -1.4. The probability comes out to be 0.0808
Thus, the <span>probability that the strawberry weighs less than 8.5 grams is 0.0808</span>

Answer:
Step-by-step explanation:
It is true that for any given odd integer, square of that integer will also be odd.
i.e if is and odd integer then
is also odd.
In the given proof the expansion for is incorrect.
By definition we know,
∴
Now, we know and
will be even values
∴ will be odd
hence will be odd, which means
will be odd.
