Altogether balls 4+2+3+5=14
P(red)=4/14=2/7
P(green)=2/14
P(yellow)=3/14
P(blue)=5/14
because it goes with replacement these probabilities are constant
Answer:
20/28.
Step-by-step explanation:
We subtract the numerators to get 21-1 = 20. The denominators stay the same at 28. We have. 21/28 - 1/28 = (21-1)/28
