Question

there are 4 red cubes, 3 blue cubes, 2 green cubes, and 1 yellow cube. if you pick 2 cubes at random with replacement. what is probability of choosing red, then choosing yellow?

Answer 1

All together are 10 cubes
Red=4 and yellow=1
Add 4+1= 5
5/10= 1/2 or .5 or 50%

Answer 2

there are 4 reds out of 10 so the probability for a red would be 4/10 and for a yellow it would be 1/10. multiply them together to get 4/100 so your probability would be 1/25 or 0.04 or 4%
