A. I think the answer is
40/200 since there are 40 blue & 200 all together That reduces into 1/5 B. I think that the answer would be 2/200 since there is 2 pieces beimg chosen and 200 all together That reduces into 1/100? C. I think that the probabilty of them both being yellow is 50/200 |

Ok
B. If two pieces of bubble gum are purchaced and the first place is green, what is the probabilty the socond piece will be white? Show all work and explain. *30 pieces are green *45 pieces are white The probability of the second one being white is 45/170 Because since the green was already chosen, I took away 30 from 200 & there is 45 pieces of white. C. If two pieces of bubble gum are purchased, what is the probability that both will be yellow? Show all work and explain. *50 pieces are yellow I think that since they are 2 yellows being chosen and there are 50 of them all together would that be either 2/50 or umm 25/200? |
