each bag below has 8 marbles. mary closes her eyes and picks a marble from each bag. bag a has 7 yellow marbles and 1 red marble. bag b has 1 yellow marble, 2 red marbles, and 5 blue marbles. bag c has 8 yellow marbles. picking a yellow marble from bag a is _____. certain likely unlikely impossible picking a yellow marble from bag b is _____. certain likely unlikely impossible picking a yellow marble from bag c is _____. certain likely unlikely impossible
Answer
Explanation:
Step1: Calculate probability for Bag A
The probability of picking a yellow marble from Bag A is $\frac{7}{8}$ since there are 7 yellow marbles out of 8 total marbles. Since $\frac{7}{8}$ is close to 1, it is likely.
Step2: Calculate probability for Bag B
The probability of picking a yellow marble from Bag B is $\frac{1}{8}$ as there is 1 yellow marble out of 8 total marbles. Since $\frac{1}{8}$ is close to 0, it is unlikely.
Step3: Calculate probability for Bag C
The probability of picking a yellow marble from Bag C is $\frac{8}{8}=1$ as all 8 marbles are yellow. So it is certain.
Answer:
Picking a yellow marble from Bag A is likely. Picking a yellow marble from Bag B is unlikely. Picking a yellow marble from Bag C is certain.
