Step-by-step explanation:
consider k the numbe of correct answers
P(k) = kC8×(0,2)^k×(0,8)^(8-k)
example:
The probability of having 2 correct answers = 2C8×(0,2)^2×(0,8)^(6) = 0.294
the probability that the number x or correct answer is fewer than 4 =
p(0) + p(1) + p(2) + p(3) = 0.944
Put the same variable on the same side first than solve

Answer:
C. For every 2 red candies in a bag, there are 3 green candies.
Step-by-step explanation:
A ratio always contains 2 figures.
Answer:
Area of triangle: 1/2*base*height
Here height= 4
Base= 8
Thus area= 1/2*4*8
=4*4
=16
