Answer:
n the left cylinder, mix 5 ml of blue and 15 ml of yellow. This is a single batch of green.
Suppose you have one batch of green but want to make more. Which of the following would produce the same shade of green?
If you're unsure, try creating the mixture in the right cylinder. Start with the amounts in a single batch (5 ml of blue and 15 ml of yellow) and . . .
add 20 ml of blue and 20 ml of yellow
double the amount of blue and the amount of yellow

Answer:
B(0.7, 100)
Step-by-step explanation:
Probability of contracting a certain disease = 0.70
No of individual randomly selected = 100
Contracting the disease is a positive/success in this case, hence
p = 0.7 and since there are 100 selection, the binomial distribution B(0.7, 100)
Hence, the The random variable describing the number of individuals who will contract the disease is B(0.7, 100) distribution.
And Mean = 0.7 x 100 = 70
