Question

In a recent poll, 70% of people order
toppings on their pizza.
Ten people chosen at random are asked if
they order toppings.
Find the probability that exactly 3 people
said yes.

Answer 1

Answer:

I'm not totally sure this is a VERY tricky question but I do know that 3 people did not say yes.

Step-by-step explanation:

Well if 70% of people said that they order toppings on pizza, then 30% don't order toppings. Therefore out of 10 people, 7 order toppings and 3 don't.
