Answer 1

ANSWER

from Least likely to Most likely

Event 3,

Event 1,

Event 4,

Event 2

Explanation

BAG A contains:

no of white marbles = 11

no of blue marbles = 9

Total marbles in Bag A

= 11 + 9 = 20

Prob. of choosing a white marble in Bag A

= 11 / 20

Prob. of choosing a blue marble in Bag A

= 9 / 20

BAG B contains:

no of white marbles = 6

no of blue marbles = 2

Total marbles in Bag B

= 6 + 2 = 8

Prob. of choosing a white marble in Bag B

= 6 / 8

Prob. of choosing a blue marble in Bag B

= 2 / 8.

Event 1: Choosing blue marble from Bag B

= 2 / 8 = 0.25

Event 2: Choosing white marble from Bag B

= 6 / 8 = 0.75

Event 3: Choosing purple marble from Bag A

= 0 / 20 = 0

Event 4: Choosing white marble from Bag A

= 11 / 20 = 0.55.

Hence, from Least likely to Most likely we have Event 3, Event 1, Event 4, Event 2.
