Another one for you!?
John has a 25% chance of missing his target with his arrow.
1. How many times would you expect john to hit the target in 120 shots
Answers:
90
120*0.75=90 times
I'm no Einstein but would guess that if he hits the target 75% of the time, you would therefore expect him to hit it 90 times (75% of 120).
I would have thought it'd be 90 times because thats 75%, but thats assuming that if he doesn't miss the target he actually hits it
90
120 (1-0.25) = 90

90. A 25% chance of missing gives a 75% chance of hitting which is three quarters. 3/4's of 120 is 90. Simple.
he will be shot first! because 75% hi missed! tell him not to join the army! poor sniper!
Gemma. Do you really want to be unemployed when you are older? You aren't learning anything this way. Why don't you try asking how these things are worked out so you actually learn something.
Also the maths you are putting up here is pretty basic to anyone over the age of 10. Wouldn't you actually like to be able to do it? I am happy to help you if you email me but really you are only cheating yourself this way.
120 (total shots ) X 0.75 (=1- 0.25 chances of missing the target) = 90 times
ONCE AGAIN, DO YOUR OWN BLOODY HOMEWORK!!
