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
