Scientifict notation is (number greater than or equal to 1 and less than 10) times 10^x
count where the decima place would make the number less than 10 and more than or equal to 1
7 places
so move the decimal place to the left 7 places and put that as the x
1.52 times 10^7 is the answer

Hi,

You just have to change z^25 to z^24 or z^27.

$C(5,4)(.40)^4(1-.40)^1=5(.4)^4(.6)^1=0.0768$

That's 7.68% = 7.7% (rounded)

Note: C(5, 4) is the number of combinations of 5 things taken 4 at a time. You may have seen this written as $_5C_4$

In general, $C(n,r)=\frac{n!}{r!(n-r)!}$
