Answer:
It is binomial:
p= 0.75 = 75%
1-p = 0.25 = 25%
N = 10
k=7
"seven successes in 10 trials"
(10 choose 7) (0.75)^7 ( 0.25)^3 =
(10*9*8 / 3*2) * (0.75)^7 ( 0.25)^3 =
(5*3*8) (0.75)^7 ( 0.25)^3
120 (0.75)^7 ( 0.25)^3
= 0.25028228759765625
or just over 25%
Step-by-step explanation:
Probably a C-, but it depends on how many other grades are in the gradebook and the exact percentage of your grade.

<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
In exponents,
When the base is same, exponents can be added
Which means,
Therefore,
Thus the given expression as single exponent is:
