D and 3, sorry if wrong hahaha
Answer:
Probability that both of them use it = 0.3945
Step-by-step explanation:
Given:
Student use app = 63%
Number of chosen student = 2
Computation:
Assume total number of student = 100%
So, probability that both of them use it.
⁶³C₂ / ¹⁰⁰C₂

Therefore, probability that both of them use it = 0.3945

Answer:
Everything except the last one about rigid transformations. Rigid transformations change the shape in size or the shape completely.
We just had to add exponents
so when we add them we get two
so,
it is a binomial
