I have a two part question that I'd like to ask.
There are {x} green blocks and {y} red blocks in a bag.
1) What is the probability of selecting a green block?
A) {x} / {y}
B) {y} / {x}
C) {x} / {={x} + {y}}
D) {y} / {={x} + {y}}
2) If 2 green blocks are removed, is there a greater probability of drawing a red or a green block?
A) Green blocks
B) Red blocks
C) Equal chance of each
I have no problem with question 1, but question 2 has flummoxed me because I need to use a formula to determine whether the answer is correct or not:
A) {=if({={x} - 2}>{y}, 100%, 0%)}
B) {=if({={x} - 2}<{y}, 100%, 0%)}
C) {=if({={x} - 2}=={y}, 100%, 0%)}
I have a feeling the answer is "No"... Can it be done?
