A person tosses a coin 9 times. In how many ways can he get 3 heads? The equation is up above I’m not sure how to use it

if he/she tosses the coin 9 times i am pretty sure he/she out of 5/9 he/she will get heads

Step-by-step explanation:

1 if he flips the coin 9 times and it spins and it flips i am pretty sure a couple times he/she will get tails or heads 2 but there is a way for him/her to get heads it flips and spins he/she is most likey to get heads 3 if he/she flips the coin and the coin keeps going the coin will flip and he/she will get heads hope this helps you :)

add both sides by 9

divide both sides by 4

we get

so far i think you have the right thing going for you just remember soh cah toh
