Answer: 8/12% 6/11%
Step-by-step explanation: so 4 red marbles and 8 blue marbles so in total that's 12 marbles so if you have 8 blue marbles you have a 3/4 chance of getting blue but only 1/4 chance of red
So 5 green marbles and 6 yellow marbles so in total that's 11 marbles so if you have 6 yellow marbles you have a 3/4 chance of getting yellow but only 1/4 chance of green
Momentum = mass (kg)*velocity (m/s)
the bullets momentum is 0.05*500=25
25/0.25=100 so the ball would have to travel at 100 m/s
Hope this helps :)
