Question

You will flip a coin five times. How many ways can you get three heads and two tails?

Answer 1

Answer:

10 ways, 6th row

Step-by-step explanation:

You will flip a coin five times and get three heads and two tails. You can get it in

$C_5^3=\dfrac{5!}{3!(5-3)!}=\dfrac{1\cdot 2\cdot 3\cdot 4\cdot 5}{1\cdot 2\cdot 3\cdot1\cdot 2}=10$

different ways.

6th row tells her the number of favorable outcomes for this event.
