Answer:40%
Step-by-step explanation:
Given
The zoo featured 6 whales exhibits
There are 15 exhibits in total
Percentage of Zoo's exhibits featuring whales
X = 68
Since the angle opposite of it is a right angle, we know that 22 + x has to equal 90 also.
So just take 90 - 22 = 68 degrees
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%
